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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The Search (/) command searches for a regular expression in a
     source file.
 
     "Regular expressions" are patterns of characters that may match
     one or many different strings. The use of patterns to match more
     than one string is similar to the DOS method of using wild-card
     characters in file names. CodeView's regular expressions use a
     subset of the UNIX syntax supported by the Programmer's WorkBench
     (PWB).
 
     If you enter the Search command with a regular expression, CodeView
     searches the source file for the first line containing the
     expression. If you do not give a regular expression, CodeView
     searches for the next occurrence of the last regular expression
     specified.
 
     You can use the Search command without understanding
     regular expressions. Since text strings are the simplest form of
     regular expressions, you can enter a string of characters as the
     expression you want to find. For example, you can enter
 
          COUNT
 
     if you want to search for the word 'COUNT' in the source file.
 
     In regular expressions, the following characters have special
     meanings:
 
     Backslash        (\)     Period           (.)
     Asterisk         (*)     Dollar sign      ($)
     Left bracket     ([)     Caret            (^)
 
     To find strings containing these characters, you must precede the
     characters with a backslash (\); this cancels their special
     meanings. For example, use
 
          x\*y
 
     to find
 
          x*y

     In Source windows, CodeView starts searching at the current
     cursor position and places the cursor at the next line containing
     the regular expression. The search wraps to the beginning of the
     file if necessary.
 
     In the command window, CodeView starts searching at the last
     source line displayed. It displays the source line in which the
     expression is found.
