Looks like this thread is more about the RAMBOX but just for completion sake - yes, using the Expanded register functions (YSTO, YRCL, etc...) has a more demanding byte consumption. However you have more standard memory for your program code - since no standard DATA registers are needed.

Answer coming from the creator of the module ... what can you ask more.
I had not seen the implied question and thus never answered it.
Thank you Àngel.

Tough to do a determinant of a 20x20 matrix any other way. :-)

Very true indeed, thanks for pointing it out!

BTW the registers directly accessible by YSTO, YRCL... are limited by the standard prompt field, of three characters - from 000 to 999. Using EEX opens up a fourth field with a leading "1", thus up to 1999 max. So the current 1,024 could be upped to 2,048 (or even 3,096) like it is the case with the SandMatrix 4Y - where the registers are managed by the matrix functions instead...
