RAM shortage

Archiver

This is probably a common problem, but I am new to Stamps, and would
like to understand if there is a work around. I have developed three
programs to accomplish a task, but when combined, I am running out of
RAM. Can I access these programs separately and pass variables to
get around my RAM limitation? I understand that the Stamp I have,
BS2P40 has the capability of running separate programs, but I don't
know if this would allow me access to more RAM.

If you're combining programs you might want to look for a way to combine
temporary variables. Most programs have them and there's no point in holding
onto the data if it isn't necessary.

Another thing to do is make sure you're using the proper type for the data
your variable stores. For example, if a variable will never do anything but
count to 10, there is no point in making it a Byte when Nibble (Nib) will
hold the information. This frees up four valuable bits.

Finally, you can save variables to the Scratchpad RAM area (with PUT) and the
retrieve them later (with GET). This is often used as a communications
mechanism when switching program banks, but it can also be used as a
temporary storage space.
