       *  RPG ILE PROGRAM CGIDEV2/UPLOADVAL
       *
       *  Sample validation program for file upload
       *
       *  This program demonstrates the ability to validate file uploads,
       *  by allowing to upload only files with extension CSV.
       *
       *  To enable this validation program:
       *  - enter command CGIDEV2/UPDEXITP (Update Exit Points)
       *  - use option 2=Change for exit point FILE-UPLOAD-001 and press Enter
       *  - in field named "User program" type UPLOADVAL
       *  - in field named "Library" type CGIDEV2
       *  - press Enter to perform the update
       *  - press F3 to exit
       *
       *  Create the program as follow:
