Forms 3.0 fortran user-exit problem

Well, to make a long story short, ORACLE support won't return my phone calls about a logged TAR; can't even get a call back after raising the prioity to critical. It's been 10 days now and the TAR still hasn't been assigned to anyone yet so I am going to try the net to see if anyone can answer my question.

The basic problem is that when I compile a Pro*FORTRAN user exit into forms 3.0 and execute it it will core dump whenever I try to open a file and write to it. I know that a Pro*C user exit will work fine, but can't seem to get a FORTRAN to work. The user exit I am using is the sample concat.pfo one that gets delivered and I am just adding in a few lines of code to open a file, write a text string to it, and close the file. When the user exit fires, it creates the file, but core dumps before anything gets written to it. By the way, the user exit works fine without my additional code so I know that the problem is in what I am trying to do.

Here is my code section that is causing the problems:

       EXEC SQL BEGIN DECLARE SECTION
           LOGICAL*1  VALUE(81)
           LOGICAL*1  FINAL(241)
           LOGICAL*1  FIELD(81)
       EXEC SQL END   DECLARE SECTION

       OPEN(23,FILE='logfile',STATUS='UNKNOWN')
       WRITE(23,10) 'CONCAT was called'
10     FORMAT(A25)
       CLOSE(23)

C      Initialize variables.
C
       DO 1 I=1,81
          FIELD(I) = ' '
1         VALUE(I) = ' '

Any suggestions?????

Thanks,
