If your env variable was merely set, like this:
  file=myfile1234.txt
and not set & exported, like this:
  file=myfile1234.txt ; export file 

Then $file would work at the command line and not in any child processes.
When you run say rreport or rclerk, that's a child process of your shell.
add a command "export file" before your clerk/report/runmenu/p/whatever
and then getenv("file") will work inside filepro.
