Calling Progress 4GL Programs from OS/400 HLL Programs
Progress/400 provides a set of commands that allow OS/400 HLL (High Level Language) programs to call Progress 4GL programs running on the Native 4GL Client. This set of commands does the following:
- The PROCALL program calls the Progress 4GL program.
- The EPI ENTRY and EPI EXIT commands allow parameters to be input to the 4GL program and output to the HLL caller.
For more information on EPI, see Progress 4GL Interfaces to OS/400 Languages and Objects."
