4 groff_ms \- groff ms macros
15 The groff ms macros are intended to be compatible with the 4.3
17 Unix ms macros subject to the following limitations:
19 the internals of groff ms are not similar to the internals of Unix ms
20 and so documents that depend upon implementation details of Unix ms
21 may well not work with groff ms;
23 there is no support for typewriter-like devices;
25 Berkeley localisms, in particular the
29 macros, are not implemented;
32 does not provide cut marks;
34 multiple line spacing is not allowed
35 (use a larger vertical spacing instead);
37 groff ms does not work in compatibility mode (eg with the
41 the error-handling policy of groff ms
42 is to detect and report errors,
43 rather than silently to ignore them.
45 The groff ms macros make use of many features of
47 and therefore cannot be used with any other troff.
49 Bell Labs localisms are not implemented in either the
51 ms macros or in the groff ms macros.
53 Some Unix ms documentation says that the
57 number registers can be used to control the column width and
58 gutter width respectively.
60 These number registers are not used in groff ms.
62 Macros that cause a reset set the indent.
63 Macros that change the indent do not increment or decrement
64 the indent, but rather set it absolutely.
65 This can cause problems for documents that define
66 additional macros of their own.
67 The solution is to use not the
69 request but instead the
77 is set to 1 by the groff ms macros,
78 but is not used by the Unix ms macros.
79 It is intended that documents that need to determine whether
80 they are being formatted with Unix ms or groff ms make use of this
83 Footnotes are implemented so that they can safely be used within
85 Automatically numbered footnotes within floating keeps are
87 It is safe to have another
93 it is required only that each
95 occur after the corresponding
97 and that the occurrences of
99 are in the same order as the corresponding occurrences of
106 can be used to begin and end a superscript.
108 Some Unix V10 ms features are implemented.
114 macros can have an optional third argument which will be printed
115 in the current font before the first argument.
120 that changes to a constant-width font.
122 The following strings can be redefined to adapt the groff ms macros
123 to languages other than English:
126 .ta \w'REFERENCES'u+2n
129 REFERENCES References
131 TOC Table of Contents
146 The font family is reset from the string
148 at initialization if this string is undefined it is set to the current
150 The point size, vertical spacing, and inter-paragraph spacing for footnotes
151 are taken from the number registers
156 at initialization these are set to
161 respectively; however, if any of these registers has been defined
162 before initialization, it will not be set.
164 Right-aligned displays are available with
169 The following conventions are used for names of macros, strings and
171 External names available to documents that use the groff ms
172 macros contain only uppercase letters and digits.
173 Internally the macros are divided into modules.
174 Names used only within one module are of the form
175 .IB module * name\fR.
176 Names used outside the module in which they are defined are of the form
177 .IB module @ name\fR.
178 Names associated with a particular environment are of the form
179 .IB environment : name;
180 these are used only within the
185 does not have a module prefix.
186 Constructed names used to implement arrays are of the form
187 .IB array ! index\fR.
188 Thus the groff ms macros reserve the following names:
199 names containing only uppercase letters and digits.
