Hi Pramod,
Uniface 8 is not anymore supported since years and few more details on how your application is installed and configured could help.
Anyhow, it is an application!
Supposing your is an application with an UI (User Interface) and NOT a pure batch application starting from command line, any tool able to capture and replay with the User Interface (CHAR or WINDOWS) used from your application should do the trick; I made a quick google session for you:
- WINDOWS provide out of the box "Step Recorder" also called "Problem Step Recorder" in Win7.
- Almost all CHAR terminal emulator packages include the functionality you are looking for.
If these two ideas do not fit your needs you can find many others starting to google with "capture replay" keywords.
If your application is a pure batch application started from command line I feel you should dig/learn how to pass parameters to it.
It's just a starting but I hope it helps!
