They are, in all respects but two, identical. The differences are: <p> <ol> <li>headers appear in the margin <em>above</em> running text while footers appear in the margin <em>beneath</em> running text; <li>the (optional) rule that separates headers from running text appears <em>below</em> the header while the (optional) rule that separates footers from running text appears <em>above</em> the footer. </ol> <a name="HEADERFOOTER"></a> <p> Because headers and footers are virtually identical, this documentation addresses itself only to headers. In all cases, unless otherwise noted, descriptions of headers describe footers as well. <p> Furthermore, any <a href="definitions.html#TERMS_CONTROLMACRO">control macro</a> that begins with <strong>HEADER_</strong> may be used to control footers, simply by replacing <strong>HEADER_</strong> with <strong>FOOTER_</strong>. <p> <strong>Author's note:</strong> Left to their own devices (i.e. if you're happy with the way <strong>mom</strong> does things by default), headers are something you never have to worry about. You can skip reading this section entirely. But if you want to change them, be advised that headers have more macros to control their appearance than any other document element. The text of this documentation becomes correspondingly dense at this point. <a name="PAGINATION_NOTE"></a> <p> <strong>NOTE:</strong> While the single page number that <strong>mom</strong> generates in either the top or bottom margin above or below running text is technically a kind of header/footer, <strong>mom</strong> and this documentation treat it as a separate page element. <p> <a name="DESCRIPTION_GENERAL"><h3><u>General description of headers/footers</u></h3></a> <p> Headers comprise three distinct parts: a left part, a centre part, and a right part. Each part contains text (a "string") that identifies some aspect of the document as a whole. <p> The left part ("header left") lines up with the document's left margin. The centre part ("header centre") is centred on the document's line length. The right part ("header right") lines up with the document's right margin. Not all parts need contain a string, and if you don't want headers at all, you can turn them off completely. <p> <strong>A note to groff experts:</strong> Although <strong>mom</strong>'s headers resemble the three-part titles generated by <code>.tl</code>, they're in no way related to it, nor based upon it. <code>.tl</code> is not used at all in <strong>mom</strong>. <p> Normally, <strong>mom</strong> fills headers with strings appropriate to the document type selected with <a href="docprocessing.html#DOCTYPE">DOCTYPE</a>. You can, however, supply whatever strings you like -- including page numbers -- to go in any part of headers. What's more, you can set the family, font, size and capitalization style (caps or caps/lower-case) for each header part individually. <p> By default, <strong>mom</strong> prints a horizontal rule beneath headers to separate them visually from running text. In the case of footers, the rule is <em>above</em> running text. You can increase or decrease the space between the header and the rule if you like (with <a href="#HDRFTR_RULE_GAP">HEADER_RULE_GAP</a>), or remove it completely. <p> <a name="HEADER_STYLE"><h3><u>Default specs for headers/footers</u></h3></a> <p> <strong>Mom</strong> makes small type adjustments to each part of the header (left, centre, right) to achieve an aesthetically pleasing result. The defaults are listed below. (The strings <strong>mom</strong> puts by default in each part are explained in <a href="docprocessing.html#DOCTYPE">DOCTYPE</a>.) <p> <strong>NOTE:</strong> Except for capitalization (all caps or caps/lower-case), these defaults apply only to <a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE TYPESET</a>. <p> <pre> TYPE SPEC HEADER LEFT HEADER CENTER HEADER RIGHT --------- ----------- ------------- ------------ Family document default document default document default Font roman italic roman Colour (black) (black) (black) All caps no no yes Size* -.5 (points) -.5 (points) -2 (points) (-2 if all caps) (-2 if all caps) (-.5 if not all caps) *Relative to the point size of type in paragraphs </pre> You can, of course, change any of the defaults using the appropriate control macros. And should you wish to design headers from the ground up, <strong>mom</strong> has a special macro, <a href="#HDRFTR_PLAIN">HEADER_PLAIN</a>, that removes all type adjustments to headers. The straightforward type specs for paragraphs are used instead, providing a simple reference point for any alterations you want to make to the family, font, size and capitalization style of any header part. <p> <a name="VERTICAL_SPACING"><h3><u>Vertical placement and spacing of headers/footers</u></h3></a> <p> As explained in the section on <a href="typedocmac.html">typesetting macros in document processing</a>, the top and bottom margins of a <strong>mom</strong> document are the vertical start and end positions of <a href="definitions.html#TERMS_RUNNING">running text</a>, not the vertical positions of headers or footers, which, by definition, appear in the margins <em>above</em> (or below) running text. <p> The vertical placement of headers is controlled by the macro <a href="#HDRFTR_MARGIN">HEADER_MARGIN</a>, which establishes the <a href="definitions.html">baseline</a> position of headers relative to the <em>top</em> edge of the page. The header rule, whose position is relative to the header itself, is controlled by a separate macro. <strong>FOOTER_MARGIN</strong> establishes the baseline position of footers relative to the <em>bottom</em> edge of the page. <p> <a href="#HDRFTR_GAP">HEADER_GAP</a> establishes the distance between headers and the <em>start</em> of running text (effectively making <strong>HEADER_MARGIN + HEADER_GAP</strong> the top margin of running text unless you give <strong>mom</strong> a literal top margin (with <a href="typesetting.html#T_MARGIN">T_MARGIN</a>), in which case she ignores <strong>HEADER_GAP</strong> and starts running text at whatever top margin you gave. <strong>FOOTER_GAP</strong> and <a href="typesetting.html#B_MARGIN">B_MARGIN</a> work similarly, except they determine where running text <em>ends</em> on the page. (See <a href="#FOOTER_MARGIN">FOOTER MARGIN AND BOTTOM MARGIN -- VERY IMPORTANT!</a> for a warning about possible conflicts between the footer margin and the bottom margin.) <p> Confused? <strong>Mom</strong> apologizes. It's really quite simple. By default, <strong>mom</strong> sets headers 4-1/2 <a href="definitions.html#TERMS_PICASPOINTS">picas</a> down from the top of the page and starts running text 3 picas (the <strong>HEADER_GAP</strong>) beneath that, which means the effective top margin of running text is 7-1/2 picas (visually approx. 1 inch). If you give <strong>mom</strong> a literal top margin (with <a href="typesetting.html#T_MARGIN">T_MARGIN</a>), she ignores the <strong>HEADER_GAP</strong> and starts running text at whatever top margin you gave. <p> Footers are treated the same way, the only difference being the default distances. <strong>Mom</strong> sets footers 3 picas up from the bottom of the page, and interrupts the processing of running text 3 picas (the <strong>FOOTER_GAP</strong>) above that (again, visually approx. 1 inch). If you give <strong>mom</strong> a literal bottom margin (with <a href="typesetting.html#B_MARGIN">B_MARGIN</a>), she ignores the <strong>FOOTER_GAP</strong> and interrupts the processing of running text at whatever bottom margin you gave. <p> If <strong>mom</strong> is paginating your document (she does, by default, at the bottom of each page), the vertical spacing and placement of page numbers, whether at the top or the bottom of the page, is managed exactly as if the page numbers were headers (or footers), and are controlled by the same macros. See <a href="#PAGINATION">Pagination control</a>. <p> <hr> <!========================================================================> <a name="HEADFOOT_MANAGEMENT"> <h2><u>Managing headers/footers</u></h2> </a> <p> The following are the basic macros for turning <a href="definitions.html#TERMS_HEADER">headers</a> or <a href="definitions.html#TERMS_FOOTER">footers</a> on or off. They should be invoked prior to <a href="docprocessing.html#START">START</a>. <p> By default, <strong>mom</strong> prints page headers. If you turn them off, she will begin <a href="definitions.html#TERMS_RUNNING">running text</a> on each page with a default top margin of 6 <a href="definitions.html#TERMS_PICASPOINTS">picas</a> unless you have requested a different top margin (with <a href="typesetting.html#T_MARGIN">T_MARGIN</a>) prior to <a href="docprocessing.html#START">START</a>. <p> Please note that headers and footers are mutually exclusive. If headers are on, footers (but NOT bottom-of-page numbering) are automatically turned off. Equally, if footers are on, headers (but NOT top-of-page numbering) are automatically turned off. Thus, if you'd prefer footers in a document, you need only invoke <a href="#FOOTERS">FOOTERS</a>; there's no need to turn headers off first. <p> <!---HEADERS---> <hr width="66%" align="left"> <p> <a name="HEADERS"></a> <nobr>Macro: <strong>HEADERS</strong> toggle</nobr> <p> <a href="definitions.html#TERMS_HEADER">Page headers</a> are on by default. If you don't want them, turn them off by invoking <strong>HEADERS</strong> with any argument (<strong>OFF, QUIT, END, X...</strong>), e.g. <p> <pre> .HEADERS OFF </pre> <p> <strong>NOTE:</strong> <strong>HEADERS</strong> automatically disables <a href="definitions.html#TERMS_FOOTER">footers</a> (you can't have both), but not the page numbers that normally appear at the bottom of the page. <p> <strong>ADDITIONAL NOTE:</strong> If <strong>HEADERS</strong> are <strong>OFF</strong>, <strong>mom</strong>'s normal top margin for <a href="definitions.html#TERMS_RUNNING">running text</a> (7.5 <a href="definitions.html#TERMS_PICASPOINTS">picas</a>) changes to 6 picas (visually approx. 1 inch). This does NOT apply to the situation where footers have been explicitly turned on (with <a href="#FOOTERS">FOOTERS</a>). Explicitly invoking footers moves page numbering to the top of the page, where its placement and spacing are the same as for headers. (I.e. the top margin of running text remains 7.5 picas.) <p> <!---FOOTERS---> <hr width="66%" align="left"> <p> <a name="FOOTERS"></a> <nobr>Macro: <strong>FOOTERS</strong> toggle</nobr> <p> <a href="definitions.html#TERMS_FOOTER">Page footers</a> are off by default. If you want them instead of <a href="definitions.html#TERMS_HEADER">headers</a> (you can't have both), turn them on by invoking <strong>FOOTERS</strong> without an argument, e.g. <p> <pre> .FOOTERS </pre> <p> <strong>FOOTERS</strong> automatically disables headers, and <strong>mom</strong> shifts the placement of page numbers from their normal position at page bottom to the top of the page. <p> <strong>NOTE:</strong> By default, when footers are on, <strong>mom</strong> does not print a page number on the first page of a document, nor on first pages after <a href="rectoverso.html#COLLATE">COLLATE</a>. If you don't want this behaviour, you can change it with <a href="#PAGENUM_ON_FIRST_PAGE">PAGENUM_ON_FIRST_PAGE</a>. <p> <!---FOOTER_ON_FIRST_PAGE---> <hr width="66%" align="left"> <p> <a name="FOOTER_ON_FIRST_PAGE"></a> <nobr>Macro: <strong>FOOTER_ON_FIRST_PAGE</strong> toggle</nobr> <p> If you invoke <a href="#FOOTERS">FOOTERS</a>, <strong>mom</strong>, by default, does not print a footer on the first page of the document. (The <a href="definitions.html">docheader</a> on page 1 makes it redundant.) However, should you wish a footer on page 1, invoke <strong>FOOTER_ON_FIRST_PAGE</strong> without any argument. <p> <hr> <!---USERDEF_HDRFTR---> <a name="USERDEF_HDRFTR"> <h2><u>User-defined, single string recto/verso headers/footers</u></h2> </a> <a name="USERDEF_HDRFTR_INTRO"><h3><u>Introduction</u></h3></a> Sometimes, you'll find you can't get <strong>mom</strong>'s handling of 3-part headers or footers to do exactly what you want in the order you want. This is most likely happen when you want the information contained in the headers/footers split over two pages, as is often the case with recto/verso documents. <p> Say, for example, you want recto page headers to contain a document's author, centred, and verso page headers to contain the document's title, also centred, like this: <p> <pre> +------------------------+ +------------------------+ | Author | | Title | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | +------------------------+ +------------------------+ </pre> With <strong>mom</strong>'s standard 3-part headers, this isn't possible, even when <a href="rectoverso.html#RECTO_VERSO">RECTO_VERSO</a> is enabled. <strong>RECTO_VERSO</strong> switches the left and right parts of headers on alternate pages, but the centre part remains unchanged. <p> Any time you need distinctly different headers on alternate pages, <strong>mom</strong> has macros that let you manually design and determine what goes into headers on recto pages, and what goes into headers on verso pages. The macros are <a href="#HDRFTR_RECTO">HEADER_RECTO</a> and <a href="#HDRFTR_VERSO">HEADER_VERSO</a>. Both allow you to state whether the header is flush left, centred, or flush right, and both take a single <a href="definitions.html#TERMS_STRINGARGUMENT">string argument</a> with which, by combining text and <a href="definitions.html#TERMS_INLINES">inline escapes</a>, you can make the headers come out just about any way you want. Use of the <strong>\*[PAGE#]</strong> escape is permitted in the string argument (see <a href="#PAGE_NUMBER_INCL">Including the page number in header-left, -centre or -right</a>), and as an added bonus, <strong>mom</strong> provides a special mechanism whereby it's possible to "pad" the string as well. <p> <!---HDRFTR_RECTOVERSO---> <hr width="66%" align="left"> <p> <a name="HDRFTR_RECTOVERSO"></a> <nobr>Macro: <strong>HEADER_RECTO</strong> LEFT | CENTER | RIGHT "<header recto string>"</nobr> <br> <nobr>Macro: <strong>HEADER_VERSO</strong> LEFT | CENTER | RIGHT "<header verso string>"</nobr> <br> <p> <strong>HEADER_RECTO</strong> and <strong>HEADER_VERSO</strong> behave identically, hence all references to <strong>HEADER_RECTO</strong> in this section also refer to <strong>HEADER_VERSO</strong>. Furthermore, <strong>FOOTER_</strong> can be used instead of <strong>HEADER_</strong> to set up recto/verso footers. <p> The first argument to <strong>HEADER_RECTO</strong> is the direction in which you want the header <a href="definitions.html#TERMS_QUAD">quadded</a>. <strong>L, C</strong> and <strong>R</strong> may be used in place of <strong>LEFT, CENTER</strong> and <strong>RIGHT</strong>. The second argument is a string, surrounded by double-quotes, containing what you want in the header. <strong>HEADER_RECTO</strong> disables <strong>mom</strong>'s normal 3-part headers, therefore anything you want in the headers must be entered by hand in the string, including colours (via the <a href="definitions.html#TERMS_INLINES">inline escape</a> <a href="color.html#COLOR_INLINE">\*[<colorname>]</a>). <p> By default, <strong>HEADER_RECTO</strong> is set at the same size, and in the same family and font, as paragraph text. The control macros <a href="#HDRFTR_GLOBAL_FAMILY">HEADER_FAMILY</a> and <a href="#HDRFTR_GLOBAL_SIZE">HEADER_SIZE</a> may be used to change the default family and size. Changes to the font(s) within the string must be accomplished with the <a href="definitions.html#TERMS_INLINES">inline escapes</a> <strong>\*[ROM], \*[IT], \*[BD], \*[BDI]</strong> and <strong>\*[PREV]</strong> (see <a href="inlines.html#INLINE_FONTS_MOM">Changing fonts</a>). Additional refinements to the style of the header-recto string, including horizontal spacing and/or positioning, can also be made with inline escapes. <p> To include the current page number in the string, use the <strong>\*[PAGE#]</strong> inline. <br> <h3><u>*Padding the HEADER_RECTO/HEADER_VERSO string</u></h3> You can "pad" the header-recto string, a convenience you'll appreciate in circumstances such as the following. <p> <pre> VERSO RECTO +------------------------+ +------------------------+ | Author Page# | | Page# Title | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | +------------------------+ +------------------------+ </pre> To pad the string argument passed to <strong>HEADER_RECTO</strong>, begin and end the string (inside the double-quotes) with the caret character (<kbd>^</kbd>). Enter the pound sign (<kbd>#</kbd>) at any point in the string where you want an equalized amount of whitespace inserted. (If you're unsure what padding is, see <a href="goodies.html#PAD">Insert space into lines</a>.) Note that if you're padding the string, it doesn't matter what quad direction you give <strong>HEADER_RECTO</strong> since padding, by its nature, justifies text to the left and right margins. <p> The situation depicted above is accomplished like this: <p> <pre> .HEADER_RECTO LEFT "^\*[PAGE#]#Title^" .HEADER_VERSO LEFT "^Author#\*[PAGE#]^" </pre> Note that <strong>mom</strong> does not interpret the <kbd>#</kbd> in <strong>\*[PAGE#]</strong> as a padding marker (i.e. as a place to insert whitespace). <p> Also, notice that the argument <strong>LEFT</strong> is used in both cases. When padding a header, it doesn't matter whether you use LEFT, CENTER or RIGHT as the argument. <p> Furthermore, should you need a user-defined header of the sort provided by <strong>HEADER_RECTO</strong> and <strong>HEADER_VERSO</strong> but aren't actually printing recto/verso, you can use <strong>HEADER_RECTO</strong> to design the header that appears at the top of every page. <p> <strong>IMPORTANT:</strong> The <a href="goodies.html#PAD_MARKER">PAD_MARKER</a> macro, which changes the default pad marker (<kbd>#</kbd>) used by <a href="goodies.html#PAD">PAD</a>, has no effect on the pad marker used in the <strong>HEADER_RECTO</strong> string. If you absolutely must have a literal pound sign in your <strong>HEADER_RECTO</strong> string, use the escape sequence for the pound sign (<kbd>\[sh]</kbd>) where you want the pound sign to go. <p> <hr> <a name="HEADFOOT_CONTROL"> <h2><u>Control macros for headers/footers</u></h2> </a> Virtually every part of headers (see the paragraph on how <a href="#HEADERFOOTER">"headers" means "footers"</a> in the <a href="#HEADFOOTPAGE_INTRO">introduction to headers/footers</a>) can be designed to your own specifications. <p> <a name="INDEX_REFERENCE"> <h3><u>Header/footer control macros</u></h3> </a> <ul> <li><a href="#HDRFTR_STRINGS"><strong>STRINGS</strong></a> <ul> <li><a href="#HDRFTR_LEFT">HEADER_LEFT</a> <li><a href="#HDRFTR_CENTER">HEADER_CENTER</a> <ul> <li><a href="#HDRFTR_CENTER_PAD">HEADER_CENTER_PAD</a> -- stick some space left of right of the centre string </ul> <li><a href="#HDRFTR_RIGHT">HEADER_RIGHT</a> <li><a href="#PAGE_NUMBER_SYMBOL">Replacing header left, centre or right with the page number</a> <li><a href="#PAGE_NUMBER_INCL">Including the page number in header left, centre or right</a> </ul> <li><a href="#HDRFTR_STYLE"><strong>STYLE</strong></a> <ul> <li><a href="#HDRFTR_STYLE_GLOBAL"><strong>Global changes</strong></a> <li><a href="#HDRFTR_GLOBAL_FAMILY">HEADER_FAMILY</a> -- family for entire header <li><a href="#HDRFTR_GLOBAL_SIZE">HEADER_SIZE</a> -- size for entire header <li><a href="#HDRFTR_PLAIN">HEADER_PLAIN</a> -- disable default adjustments to header parts <li><a href="#HDRFTR_COLOR">HEADER_COLOR</a> -- colourize the header </ul> <ul> <li><a href="#HDRFTR_STYLE_PART"><strong>Part-by-part changes</strong></a> <li><a href="#_FAMILY">_FAMILY</a> -- left, centre or right family <li><a href="#_FONT">_FONT</a> -- left, centre or right font <li><a href="#_SIZE">_SIZE</a> -- left, centre or right size <li><a href="#_CAPS">_CAPS</a> -- left, centre or right all caps <li><a href="#_COLOR">_COLOR</a> -- left, centre or right colour </ul> <li><a href="#HDRFTR_VERTICAL"><strong>VERTICAL PLACEMENT AND SPACING</strong></a> <ul> <li><a href="#HDRFTR_MARGIN">HEADER_MARGIN</a> <li><a href="#HDRFTR_GAP">HEADER_GAP</a> </ul> <li><a href="#HDRFTR_SEPARATOR"><strong>SEPARATOR RULE</strong></a> <ul> <li><a href="#HDRFTR_RULE">HEADER_RULE</a> <li><a href="#HDRFTR_RULE_GAP">HEADER_RULE_GAP</a> <li><a href="#HDRFTR_RULE_COLOR">HEADER_RULE_COLOR</a> </ul> </ul> <!---HDRFTR_STRINGS---> <hr width="66%" align="left"> <a name="HDRFTR_STRINGS"><h3><u>Header/footer strings</u></h3></a> <p> <a name="HDRFTR_LEFT"> <nobr>Macro: <strong>HEADER_LEFT</strong> "<text of header left>" | #</nobr> </a> <br> <a name="HDRFTR_CENTER"> <nobr>Macro: <strong>HEADER_CENTER</strong> "<text of header centre>" | #</nobr> </a> <br> <a name="HDRFTR_RIGHT"> <nobr>Macro: <strong>HEADER_RIGHT</strong> "<text of header right>" | #</nobr> </a> <p> To change the text (the "string") of the left, centre, or right part of headers, invoke the appropriate macro above with the string you want. For example, <strong>mom</strong>, by default, prints the document's author in the header-left position. If your document has, say, two authors, and you want both their names to appear header-left, change <strong>HEADER_LEFT</strong> like this: <p> <pre> .HEADER_LEFT "R. Stallman, E. Raymond" </pre> Because the arguments to <strong>HEADER_LEFT, _CENTER,</strong> and <strong>_RIGHT</strong> are <a href="definitions.html#TERMS_STRINGARGUMENT">string arguments</a>, they must be enclosed in double-quotes. <p> <strong>NOTE:</strong> Replace <strong>HEADER_</strong>, above, with <strong>FOOTER_</strong> to change the strings in footers. <a name="HDRFTR_CENTER_PAD"><h3><u>*Padding the header/footer centre string</u></h3></a> <p> <nobr>Macro: <strong>HEADER_CENTER_PAD</strong> LEFT | RIGHT <amount of space by which to pad centre string left or right></nobr> <br> <em>*Requires a <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a></em> <p> By default, <strong>mom</strong> centres the header centre string literally on the line length in effect for page headers. In some cases, notably when the header left or header right strings are particularly long, the effect isn't pretty. The offendingly long header left or right crowds, or even overprints, the header centre. That's where <strong>HEADER_CENTER_PAD</strong> comes in. With a bit of experimentation (yes, you have to preview the document), you can use <strong>HEADER_CENTER_PAD</strong> to move the header centre string left or right until it looks acceptably centred between the two other strings. <p> For example, say your document is an outline for a novel called "By the Shores of Lake Attica." You've told <strong>mom</strong> you want <p> <a href="docprocessing.html#DOCTYPE">DOCTYPE</a> <halign="center"> <strong>NAMED</strong> "Outline" <p> but when you preview your work, you see that "Outline", in the centre of the page header, is uncomfortably close to the title, which is to the right of it. By invoking <p> <pre> .HEADER_CENTER_PAD RIGHT 3P </pre> you can scoot the word "Outline" over three <a href="definitions.html#TERMS_PICASPOINTS">picas</a> to the left (the padding's added to the right of the string) so that your head looks nicely spaced out. Invoking <strong>HEADER_CENTER_PAD</strong> with the <strong>LEFT</strong> argument obviously puts the padding on the left side of the string. <p> Most reassuring of all is that if you use <strong>HEADER_CENTER_PAD</strong> conjunction with <a href="rectoverso.html#RECTO_VERSO">RECTO_VERSO</a>, <strong>mom</strong> will pad the centre string appropriately left OR right, depending on which page you're on, without you having to tell her to do so. <p> <hr width="66%" align="left"> <p> <a name="RESERVED_STRINGS"><h3><u>Using mom's "reserved" strings in header/footer definitions</u></h3></a> <p> As pointed out in the author's note in the introduction to headers/footers, headers and footers are something you don't normally have to worry much about. <strong>Mom</strong> usually knows what to do. <p> However, situations do arise where you need to manipulate what goes in the header/footer strings, setting and resetting them as you go along. A case where you might want to do this would be if you want to output endnotes at the end of each document in a series of <a href="rectoverso.html#COLLATE">collated</a> documents, and you want the word "Endnotes" to go in the header centre position of the endnotes, but want, say, the <a href="docprocessing.html#TITLE">TITLE</a> to go back into the centre position for the next output document. <p> In scenarios like the above, <strong>mom</strong> has a number of "reserved" strings that you can plug into the <strong>HEADER_LEFT, _CENTER</strong> and <strong>_RIGHT</strong> macros.

If you don't want this behaviour, invoke the macro <strong>PAGENUM_HYPHENS</strong> with any argument (<strong>OFF, QUIT, END, X...</strong>), like this: <p> <pre> .PAGENUM_HYPHENS OFF </pre> If, for some reason, you want to turn page number hyphens back on, invoke the macro without an argument. <p> <hr> <a href="rectoverso.html#TOP">Next</a> <a href="docelement.html#TOP">Prev</a> <a href="#TOP">Top</a> <a href="toc.html">Back to Table of Contents</a> </body> </html>
