I’m setting up a little cross-program data validation. Program A does a little validation of some data which it will pass to Program B, which wants to be very strict. Since I don’t really care about the data, even once it’s in Program B, I’m trying to make Program B relax a little bit.
This has led me to this morning’s programming observation: in a billing system, maybe the main “bill” subroutine shouldn’t be over three hundred fifty lines longs.
