Thanks Hassan and Toon,

Here's some more info:
G77 Version: g77 version 2.95.2 19991024 (release) (from FSF-g77 version
0.5.25 19991024 (release))

I have tried all the -fugly options to no avail, but from the previous
comment I found
the IMPLICIT INTEGER*4 (A-Z) statements.  I was trying not to do too much
code change,
but since the -fugly compiler options aren't the solution..I guess the code
changes will
have to be done - correct?

Again, thanks for your help,
andy

I know this from experience. I got to port code written in Fortran ages
ago using g77 on linux/pc.


There is no fugly- that will let you compare chars to ints. Even IBM's
xlf does not support it. 

It should not however be hard to write an implicit function that does
it. Will take a char*something and int*same thing and do the magic of
equivalence locally to check if they are equal.

Error: must operate on two scalar (not array) subexpressions

[Andrew Stone]

Hello all,

First off, I hope I'm in the right place.  I'm working on a project
to put a DOS based system on the web. This system was written in
FORTRAN-77 (not by me) and compiled with Salford's FTN77. I'm trying
to compile this source code using g77 and get the following error:

CALC401K.FOR:194:
         IF(UNTYPE.EQ.'XX  ') GOTO 171
                  1   2
Equality operator at (1) must operate on two scalar (not array)
subexpressions, two function invocations returning arithmetic or character
scalars, or a combination of both -- but the subexpression at (2) is an
array

UNTYPE is Declared as:

COMMON/UNTYPE/UNTYPE


Any help would be greatly appreciated, I've tried different compiler
options and have not had any luck.

thanks in advance,
andy

Hi,

I guess UNTYPE is an integer*4, right?

In this case, there is no way you can compare it to a character*4,
unless you are on some very old machines with some very proprietary
compilers ;-)

The solution is:

integer*4 what1
character*4 what2 

equivalence (what1, what2)

what2 = 'XX  '

if (untype .eq. what1) .....

Are you sure you tried all compiler options starting with -fugly- .... ?

BTW, which version of the compiler are you using (send the output of g77
-v).

Thanks,
