Interesting...did not know that. I have a lot of functions in a .prg that are "lookup" functions (look up a name or company name etc) so they can be used in reports or queries etc. But usually these are looking up directly from the tables so maybe that's why I have never run into anything yet.

Thanks,
Albert

Because this is done so often, we created a prg set_dsid() that returns the DSID when called with no parameter, and when passed a parameter sets the DSID if that is not the current one.
