  • Microsoft FORTRAN PowerStation for MS-DOS 1.0

This article was previously published under Q104894


The intrinsic function VERIFY doesn't compare the last character of the character string with the character set.


Microsoft has confirmed this to be a problem in FORTRAN PowerStation for MS-DOS, version 1.0. This problem has been resolved with FORTRAN PowerStation maintenance release version 1.0a for MS-DOS.

FORTRAN PowerStation version 1.0 can be differentiated from the maintenance release version 1.0a by invoking the linker. Typing "link32 | more" from \F32\BIN directory will show version 2.8 for FORTRAN PowerStation version 1.0, and it will show version 1.0f for the maintenance release version 1.0a.


The intrinsic function VERIFY compares the characters of one string with another string.

   VERIFY (charstr, charset [,log])

Each character of charstr is compared with the charset. VERIFY returns the position of the first character in charstr that it could not find in charset. If log is true, characters are taken from charstr in reverse.

The sample code fails if compiled with FORTRAN PowerStation, but will pass with FORTRAN 5.1 and 5.0. Versions of FORTRAN before 5.0 do not have the VERIFY function.

Sample Code

C No compiler options required
      i = verify('ba','b')
      if (i.eq.2) then
        print*, 'verify correct:   ',i
        print*, 'verify incorrect: ',i
      end if
