$$IGNORE

This is a transformation that can be applied to the substitution of macro parameters content (but not macro contents).

The text will be "dropped" (transformed to an empty string). The main reason you might want to do this is if you are validating parameter use.

EXAMPLE

#define AddFileWild                                                        \
       <$HereWeAre "{$?MacName} - {$SrcDir}\{$Includes=^*.*^}">           %\
       #RexxVar  @@SrcDir = ^{$SrcDir}^  ;;Hack to handle single quotes   -\
