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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

─────$DO66──────────────────────────────────────────────────────────────────
 
     Action
 
     $DO66 causes DO statements to conform to FORTRAN 66 semantics.
 
     Syntax  $DO66
 
     Remarks
 
     You must obey the following rules when using $DO66:
 
        ■ $DO66 must precede the first declaration or executable
          statement of the file in which it occurs.
 
        ■ $DO66 may only be preceded by a comment line or another
          metacommand.
 
        ■ $DO66 may only appear once in the source file.
 
     When $DO66 is enabled, the following FORTRAN 66 semantics are used:
 
        ■ Statements within a DO loop are always executed at least
          once.
 
        ■ Extended range is permitted; control may transfer into the
          syntactic body of a DO statement.
 
     The $DO66 metacommand is equivalent to the /4Y6 compiler option.
