100 M4 is a macro processor available on
134 A macro processor is a useful way to enhance a programming language,
145 any macro processor _
148 The M4 macro processor is an extension of a macro processor called M3
150 for the AP-3 minicomputer;
151 M3 was in turn based on a macro processor implemented for [1].
177 M4 provides a collection of about twenty built-in
181 Built-ins and user-defined macros work exactly the same way, except that
182 some of the built-in macros have side effects
195 is `\-',
209 The primary built-in function of M4
249 If a macro or built-in name is not followed immediately by `(',
258 if it appears surrounded by non-alphanumerics.
403 the quote characters can be changed with the built-in
414 There are two additional built-ins related to
417 removes the definition of some macro or built-in:
424 Built-ins can be removed with 
432 The built-in 
435 In particular, M4 has pre-defined the names
461 User-defined macros may also have arguments, so different invocations

541 Arithmetic Built-ins
543 M4 provides two built-in functions for doing arithmetic
560 The more general mechanism for arithmetic is a built-in

712 To facilitate making unique file names, the built-in
722 There is a built-in called
727 ifelse(a, b, c, d)
732 .UL b .
