HP 35s Programming Question

[Dave Britten]

That's because in the 35S, and most of its predecessors, there is only one memory space. You can put multiple programs in memory by using multiple labels, each label being a different entry point. So you can either go to the top or bottom of program memory, add a LBL B, and start entering another program.

The 41C and 42S are the only two HP RPN calculators I can think of off the top of my head that use END to partition multiple independent program areas in memory. The unreleased HP 95C was to have something kind of similar, but simpler.
