It might also mean that if you have an old program that uses lots of registers and stores it's results on the stack, then you might be able to run it cleanly by doing LSTO "REGS" and then calling the program.

You even can create temporary "REGS" for use in manual mode only

Code:


01 LBL "AREGS"
02 NEWMAT
03 LSTO "REGS"
04 STOP
05 RTN

Put your desired nRows and 1 on the STACK and run AREGS. After that you'll have that new set of registers available until you hit R/S, this will invoke RTN and thus reactivate the standard REGS.

But wait a minute. Before you hit R/S you could save your "local" REGS as a normal VAR e.g. "REGS1" for later use. Then when you sometime later want to reactivate "REGS1" just recall it and LSTO it to "REGS" but then to return to the original "REGS" you have to do a RTN. GTO .. does it also.

Cool? Günter
