In the M/MEP Editor version 1.02, there is a problem in the MGREP
function; it will fail to find some matches to the query in the file.
(This is due to certain regular-expression matches failing when they
shouldn't.) Below is a macro that will use the MEGREP.EXE utility to
search for a string, and return the results in the compile window. The
benefits are:

1. It should be faster, especially under OS/2.

2. If run under OS/2, it will be a background process enabling you
   to continue working.

Macro Code
----------

Add the following to your TOOLS.INI file. You can then assign it to a
keystroke, if desired:

megreplist:="*.c *.h"
mg1:=copy arg "<megrep>" setfile mark emacsnewl mark paste begline
mg2:="arg arg \"megrep \\\"" endline "\\\" " megreplist
mg3:=" \" compile" begline arg endline execute setfile
megrep:= mg1 mg2 mg3

The following is another option, which avoids using an extra
pseudo-file:

megreplist:="*.c *.h"
mg:= copy arg "<clipboard>" setfile            \
     begfile "megrep \"" endline "\" " megreplist  \
     begline arg arg endline compile setfile

Notes
-----

1. The first macro is in three parts due to line-length limits of the
   knowledge base; the macro could be just one line. The second macro
   uses line continuation characters to achieve the same result as
   breaking up the first macro.

2. The macro assumes that all files on disk are up to date.
