You're quite right - Last week I had the embarrassment of a user reporting this error after my app had been up and running for some time, but no one had ever accessed the seldom-used method with the SET STEP ON previously (or at least no one complained until now) :)

And now in vfp6, the breakpoint is so simple to use, SET STEP ON can be discarded, I think...
