HP-12CP Programming - Multiple programs

[ThomasF]

Yes, since the 12C has no labels and only absolute addressing, it is quite cumbersome to use with multiple programs (always have to remember the line number for each program), and make sure that changes don't overwrite other code.

But, empty blocks of lines could always be used for patches (if original program needs to be updated or expanded).
Unfortunately subroutines are not available, but patches could be used as describe on page 113 in the 12CP manual (http://h10032.www1.hp.com/ctg/Manual/bpia5309.pdf).

Cheers,
Thomas
