Re: remove program/function from custom menu

Well, no. You have to assign an empty string, not a blank. It will look the same, until you execute the assigned key. The blank will produce Label Not Found. To assign an empty string, simply do Shift-ASSIGN ENTER ENTER <key> That will effectively remove the assignment. BTW, for a blank, there’s no ...

Re: Complex matrix inversion with issues

Strange that only a single row of A*inv(A) is wrong, the second row.

Re: Complex matrix inversion with issues

Update: even Free42 v3 has the problem. e.g. A*inv(A)[2,1] = -1.2+i24.5e-3 instead of zero, or close. In CODE format, to easily turn into a RAW file: 00 { 688-Byte Prgm } 01▸LBL "CM" 02 5 03 ENTER 04 NEWMAT 05 ENTER 06 COMPLEX 07 EDIT 08 0.001 09 0 10 COMPLEX 11 → 12 0 13 0 14 COMPLEX 15 →...

Re: # 'not equals' character in multiline edit mode

Even in X#Y?, the character shows up differently. Let's see if I can capture that:

This is twice the same line X#Y?, but with the cursor on the second line.

Re: Free42 Version 3

I'm in favor of updating the DM42 to the Free42 ver.3, if it doesn't create any backward compatibility issues with programs written for 4 level stack. Some of the programs I use depend on stack lift and its also one of the reasons RPN has been my choice in calculators for 40 years. amafan: the unli...

Re: Could someone educate me on options for HEPAX RAM size?

Hi Bob, the HEPAX_8H uses only four blocks.
The ‘4’ in HEPAX_4H probably points to its dependance on Lib#4.
