Q102694: FIX: F1917 Error, Print Logical Expression of COMPLEX Values

Article: Q102694
Product(s): Microsoft Fortran Compiler
Version(s): 1.0
Operating System(s): 
Keyword(s): 
Last Modified: 24-MAR-2000

-------------------------------------------------------------------------------
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" (without the
quotation marks) 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.
