Memory management?
The memory management in the DM42 puzzles me. I had in the order of 6K bytes free, and wanted to see if a 42S trick worked on the DM42: 6K bytes is enough to hold a 10x10 complex matrix (it would take slightly more than half the memory), but you can't create it in the normal way: 10 ENTER NEWMAT ENT...

Re: minor inconsistency
But EDIT puts the content of position 1:1 into X. The matrix is returned to the stack only after EXITALL. If you re-edit the matrix after having put a 5 in, the 5 will be pushed up if you enter something new. The 'store and next' commands (up, down, left and right arrows) do disable stack lift, howe...

Re: minor inconsistency
EDIT enters the matrix at position 1:1, and the current content (a zero) gets lifted up to Y when you enter the 5, because stack lifting is enabled.. That is how the 42S behaves, and so it is faithfully reproduced in Free42 - in this case, there is no choice: programs would behave differently (wrong...

Re: minor inconsistency
Hi Bob, I use programs "T" all the time, as small tests, and usually have a dozen or so before I start cleaning them up. One of them (not the most recent) was a solver program that I needed to run again.. @Boub65: Thomas is dedicated to make Free42 behave as close to the real 42S as possib...

minor inconsistency
Suppose you have two programs with the same global label, but the older one has MVAR statements (so will be recognized by the interactive solver and integrator). The simplest way to accomplish that is: LBL "T" MVAR "X" LBL "T" END When you invoke the solver, and press &...

Re: .END. in XEQ menu
Yes, in PRGM mode, there’s no reason for GTO and XEQ to show the .END. - but the 42S does it, so..

Re: Any tricks for programs that write programs?
Hello Thomas, if you're going to add more functionality, I vote for the 'RTN+1' instruction, or RTNSKIP or whatnot, shamelessly stolen borrowed from the WP34. LSTO was already an enormous step in enabling to write routines that mimic built-in ones, and RTN+1 will allow the creation of your own tests...

Re: 3-bit flag
-- UPDATE -- : the LBL 10 was misplaced of course, plus some initialisations added okay, I think I understood now: you can only choose 1 option, A,B,C or D. And when you just entered, none have been chosen. Choosing another option will erase the previously chosen one. So, two options 1.with a variab...
