RE: hp41cx named variables in extended memory
Hi,
I'm writing two programs for 41C with X-Functions and X-Memory.

One creates a data file in X-Memory for replacing registers from 00 to 10 (it can replace any register, actually, if you get memory to hold the programm (or a NovRAM - HEPAX module).
So, operations like RCL 05 will be written as XEQ "R5"; STO 05 as XEQ "S5"
One subroutine creates the file: ALPHA: name of file; X: number of registers - XEQ "XREG"
One subroutine for each "Rn" and one for each "Sn".
It's quite a byte consumming, but works. You can get private data registers for every program.
The routine CU, in synthetic programming books is not very usefull - only for called programs: after you called it, the n registers (in main memory) will desappear to the called program. My got another way, but eats bytes...

It's already finished.

The second program is for creating a file in X-Memory for named variables (name up to six charaters) , for numeric or alpha contents. I'm writting it.
One subroutine creates the file: ALPHA: name of file XEQ "XVAR".
Two subroutines for recovering values: in ALPHA, put the name of variable. So, if numeric, XEQ "XRCL": the content will be recovered to X; if alpha, XARCL will recover content to ALPHA.
For storing data, ALPHA: name:value XEQ "XSTO", either for alpha or numeric variable.

What do you think about this idea?
Best wishes from Brazil
