I don't think it has anything to do with DO WHILE, and FOR loops. It simply indicates that the level of function calls (either with DO program or the execution of a user define function) has exceeded the limit of 128 levels. I recall that in the FP 2.x day the limitation only was about 32 levels.

>Unless you're involved in a recursive algoritm which could recurse inwards in exces of 128 layers (the limit of calling depth to a VFP application) the odds are very strong that you've misconstructed a series of embedded loops within a single process.

Yes, you're right, the error mostly occurs when some unintended recursive mechanism is involved.
