Important Notice
The pages on this site contain documentation for very old MS-DOS software,

Change Command - Regular Expressions (4 of 4)
Use the Change command to search for one text string and
replace it with another. Once made, changes cannot be
reversed; that is, the Undo command has no effect.
The replacement can be made
■ Automatically, with <Change All>, or
■ Only after you signal approval, with <Find and Verify>
To alter the matching criteria for the search:
■ Turn on a whole-word search
■ Turn on a case-sensitive search
■ Use regular expressions to change a pattern of text
To cancel the Change command, select <Cancel>.
