This is very odd, VFP 5.0 caught the error when you compiled??? This prg when compiled does not catch any errors.

*!* temp.prg

**IF .T. && or

do while .T.
messagebox('hi mom',4,"that's all")

return


Yet, when run there is a Nesting error.

Would you mind checking this again? Have you applied any patches or upgrades to 5.0?

Thanks, Kim
