This command will add \e{gflag} to the global define list. This will have a similar effect as using the /D switch on the command line (only the define only becomes effective after the !define command).

\c [/ignorecase] [/noerrors] [/file] source_string_or_file substring_start OUTPUTSYMBOL1 [substring [OUTPUTSYMBOL2 [substring ...]]]
Parses \e{source_string_or_file} (which is treated as a string, or as a filename if \e{/file} is set), looking for \e{substring_start}. If \e{substring_start} is found, then \e{OUTPUTSYMBOL1} is defined to the rest of the string (minus any other \e{substring} that may be found). Any number of \e{OUTPUTSYMBOLx} may be specified, and the final \e{substring} is optional.
If \e{/noerrors} is specified, matching less than the full number of strings is allowed (all \e{OUTPUTSYMBOLx} after the not-found substring will be ignored).
If \e{/file} is specified, the file is treated as a series of lines. The file is searched until all substrings are matched. If \e{/noerrors} is specified and not all strings are matched, the first line with the most symbols matched is used.
