OK, I know there's a boatload of smart people on this list...

When you program the PSIM from the computer, it writes the executable 
code into the PSIM (an EPROM?).  Is it possible for the program that 
is running in the PSIM to change the contents of the PSIM's memory?

Is there some way to (for example)
1) "reserve" 32 bytes for data
2) using input from a CV in, change the values in thoses bytes while 
running

Some kind of compiler directive or something?  I remember doing 
something like this in Pascal or Assembly...

There must be some way to have the PSIM hold some data values that 
are set and/or changed while it's running, and *not* lost at power-
down or reset.  The MOTM uSeq does it... surely the PSIM can!

PEEK/POKE?
