filePro currently requires that the command be specified on the USER line, 
and doesn't take any variables.

You could pass the variable to the program.  Using your example:

     user prog = /flantec/scripts/findphoto
     prog = qx      ' Pass the filename to the script
     result = prog  ' Get the result back

Then, the script would then read the name from stdin, rather than the 
command line.

     while read name
     do
         # The "real work" goes here.
     done
