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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

─────Conditional Compilation Option (/4cc)──────────────────────────────────
 
     This option conditionally compiles specific lines of source code.
 
     Syntax: /4cc<string>
 
     The /4cc option permits conditional compilation of a source file.
     The <string> is a set of alphabetic characters controlling which
     lines in the source file are to be compiled.
 
     Any line in the source file with a letter in column 1 found in
     <string> is compiled; lines beginning with other letters are
     treated as comments. All lines not beginning with letters are
     compiled normally.
 
     NOTE: Program lines with the character C or c in column 1 are
     always treated as comments.
 
     Example
 
          FL /c /4ccXYZ PRELIM.FOR
 
     In this example, all lines in the file PRELIM.FOR beginning with
     X, Y, or Z are compiled.
