Syntax:

     $[m,pattern,string]

In this transformation, NMAKE32 will return those words in string which match the filename pattern specified by pattern. The matching is case-insensitive.

A filename can contain one or more of the following patterns:

• Matches any string, including the null string.

• Matches any single character.

• Matches any one of the enclosed characters.

• Matches any character between the enclosed pair, inclusive (range)
  

  To remove the special meaning of the characters {, }, \, ., *, ^, and !, if they are part of the filename to be matched, precede them with a backslash. If the dollar ($) character is used in a pattern, it must be preceded by a caret (^) character so that it will not be interpreted as a macro. The characters [, ], and comma (,) cannot be used in pattern matching.

  Enclosed characters can be combined with ranges. Therefore, [ABCM-Z]* matches any filename that begins with A, B, C, or M through Z.

  Examples:

  The following transformation:

       $[m,*.c,x.c a.h b.h c.h]
  

  returns:

       x.c
  

  Since string can include macros as well as text, a transformation macro can be used to easily extract dependents with a particular extension. If the following line was in a description file:

       my.obj: my.c a.h b.h c.h
  

  The macro:

       $[m,*.c,$**]
  

  returns:

       my.c
