Greetings,

This is my first time posting. Generally, I've been content with just reading these forums, but I just discovered something about Free42's LSTO feature that I haven't seen mentioned anywhere and it's too exciting not to share!

This is how it started:

Code:

00 { 23-Byte Prgm }

01▸LBL "TstLSTO"

02 RCL "REGS"

03 LSTO "REGS"

...

If LSTO was used to create a local REGS, would all the commands that normally interact with REGS address that local REGS and leave the global REGS untouched?

I tried STO and RCL and their arithmetic, an assortment of STAT functions, ISG, DSE, printing the REGS, CLΣ and CLRG. I'm sure there's more, but all of these interacted with the local REGS and ignored the global one!

At the moment, I have no real need for this, but I rather like the idea that I can use the whole suite of REGS-related functions in a subroutine without worrying about their impact on previously stored data.
