ActiveVFP: Are there any example for data validation in the demo?

I have attempted to validate data input from the user by trying to use VFP function(i.e GetWordNum() or StrtoFile() )in the Main.prg but errored out on the particular Function line. What are the functions I can not use in the Main.prg?

I'm not sure why you would use those functions to validate input.

If you can't use a function in MAIN.PRG, then try to make a separate PRG file. I have very little in my MAIN.PRG.
