Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     Case (Boolean)
 
     The Case switch determines if letter case is distinguished in
     searches.
 
     The search functions that use the Case switch have 'meta' forms
     that temporarily reverse the sense of the Case switch.
     See: Meta, Mgrep, Mreplace, Msearch, Psearch, Replace

     The Unixre and Case switches have no effect on the syntax of
     regular expressions used by the Build or Word switches. These
     switches always use case-sensitive UNIX regular expressions.
     See: Build, Unixre, Word

            letters in text.
 
     no     Case is not significant in searches.
 
            Uppercase letters match lowercase letters.
