We have a system where we upload text files into an AS400 as input. Unfortunately, since the two systems, FoxPro and AS400 are quite separate, we have to give input to the AS400 in this text mode.

What I need to do is to detect that a text file has no data in it so that I can run a FoxPro program that will reverse an update flag field. The Question is How do you detect that a text file has no data in it? Use low-level commands?
