Re: WP-34S: Subroutines, local registers and hotkeys Message #8 Posted by David Hayden on 23 Aug 2013, 12:08 p.m., in response to message #5 by Marcel Samek
In addition to what Marcus said, another advantage is that it helps ensure that you don't accidentally build up a huge set of unused local registers. E.g., XEQ VTL, press the 'A' hotkey, go have lunch, XEQ VTL again, answer the phone, XEQ VTL, etc. You really want to clear the local registers each time somehow.
An alternative would have been to clear the local registers when you return control to the keyboard, but that would make debugging them impossible.
