I'm working on a Car Lock/general control system, based on a BS2p24, and I
too found I had to split the code...
What I do, is that I've set up a variable defined as Word and the first
thing the program in each slot does is to check the variable, branching to
the necessary subroutines as necessary.
I used a Word size variable(First in the list of VAR's) because of the way
the Stamp software assigns variables to the memory.
(Words first, then Byte, before Nibble and finally Bit)
That way I'm certain that it's always in the same place for all programs.
Of course I don't use all the 65535 different values of the Word, only the
LOWBYTE, and have reserved the HIGHBYTE for other status flags.
I've also set aside a separate page to contain seldomly changed data and
textstrings that I sometimes display on the LCD. (The BS2p allows this with
a STORE command to redirect the READ/WRITE commands)
