FIX: F1917 Error, Print Logical Expression of COMPLEX Values

ID: Q102694

The information in this article applies to:

Microsoft FORTRAN PowerStation for MS-DOS, version 1.0

SYMPTOMS

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

RESOLUTION

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.

STATUS

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.

MORE INFORMATION

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)
      end

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
      end

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.
