  • Microsoft FORTRAN PowerStation for MS-DOS 1.0

This article was previously published under Q102694


An attempt to compile an application that contains a logical expression that involves COMPLEX variables in the output list may fail and Microsoft FORTRAN PowerStation may generate the following message:

fatal error F1917: unknown primitive type


To avoid this error, assign the result of the logical expression to a logical variable and specify the variable instead of the expression in the output list.


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


The following sample code demonstrates this problem:

Sample Code 1

C Compiler options needed: None

      complex x, y
      x = (1.0, 1.0)
      y = (1.0, 1.0)
      print *, (x .NE. y)

The following sample code demonstrates the method to work around this problem:

Sample Code #2

C Compiler options needed: None

      complex x, y
      logical logVal
      x = (1.0, 1.0)
      y = (1.0, 1.0)
      logVal = (x .NE. y)
      print *, logVal

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.
