Error using write matrix

Hi all.

I am trying to run my script using crontab and one .sh script as "pilot".
In the script i set the NCARG_ROOT environment variable, and another
variable INST_DIR , thath i use in the scripts as "path".
I don't have problems, except if i use "write matrix":

This is the error thath i recieve as system mail :

>/home/pastore/AFS_SITE_4/afs_pilot.log

And this is the part of my scripts, where it abends:

              if (today_weekday.eq.3) then ; Write ranges to file
                   if TS.eq."A" then
                       _log("Write data on ascii file");
                       fmtf = "3f7.2" ; output format (Fortran
notation)
                       opt = True
                         opt_at_fout =
"$INST_DIR/TRN_"+abs_var(var_ix,2)+"_"+reg_ix+"_range.txt"
                         write_matrix(trn_range,fmtf,opt)
                     end if
                   _log("Write data on ascii file: DONE")
               end if

Do you have suggestions for me ?

Thanks !!

Ciao, Marco
