"Assume default machine settings" followed by "any default setting that might have been changed during program execution should be restored at program completion", or something like that. This would prevent an obedient programmer from including a line "FIX 4" (or equilavent flag settings), for instance, even if no display mode changing instruction had been used.

Then that would mean that there's no need to clear the flags at the start of the program, but would need to clear them when finished to get them back to Default Machine settings.

I'm not sure I'm a fan of this rule. I have would preferred it that there's no assumption made on the calculator initial settings. Other than registers 1-5 containing the test data.

Thanks,
