Another person and I (a long time ago) had a discussion about trying
to get the hp28s to multitask.  I think the consensus was that it
wouldn't be possible from RPL, and that we weren't sure about ML.
Since the hp48sx has about the same tasking features, I would assume
the same for it.  The real problem lies in the "stack" nature of
interrupting programs: i.e. you can interrupt a program, execute
another program, and then continue with the original, but there is no
way (that we could find) to resume an arbitrary interrupted program
(you must follow the FIFO order of the program interruption "stack").

I hope this helps.  I may be wrong, because the above was derived from
educated guessing.
