But a 67/97 programmer who needs this just so will know to rewrite his cards to adjust the header and checksum lines if other presets are needed for a program.

I just figured program should control what it needs and not depend on the calculator being in some set mode. I think it is dangerous for a program to assume that the modes have been set up correctly before running. It's just better for the program to select the display and other modes within the program listing. Unless the programmer is up against the maximum allowable steps, he should include the mode steps that his program requires.

Good point. I remember vaguely that back in the old days the HP41 Users Library wouldn't accept programs if they fooled around with the calculator's customization.

I just want to bump this, as I haven't been doing any go67c programming lately and have focussed on other things.

Anyone out there have any experience yet with Bill's excellent work?
