The information in this article applies to:
- Microsoft FORTRAN PowerStation for MS-DOS, version 1.0
-------------------------------------------------------------------------------
SYMPTOMS
========
The string comparison operators stop the comparison operation at the occurrence
of the first NUL character. The rest of the string after the first NUL character
is not compared.
RESOLUTION
==========
Use the string termination character only at the end of the string.
STATUS
======
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" (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.
MORE INFORMATION
================
The string comparison operation works correctly in Microsoft FORTRAN version
5.1. Compiling and executing the following code with PowerStation will
demonstrate the problem.
Sample Code
-----------
C No compiler options required
character*10 a,b
a = "1234567890"
b = "123456789A"
a(5:5) = char(0)
b(5:5) = char(0)
print *, "Should be: F T T T F F"
print "(' Result: ',L2,\)", ( a .eq. b )
print '(L2,\)', ( a .ne. b )
print '(L2,\)', ( a .lt. b )
print '(L2,\)', ( b .gt. a )
print '(L2,\)', ( b .le. a )
print '(L2)', ( a .ge. b )
end
