Size: 7.34 MB

What's New:

EDIT, EDITN, and INDEX now support editing lists, nested lists, empty lists, and matrices within lists. See the Free42 web site for details.
FUNC now hides the caller's RPN stack, so functions like CLST and R↓ can be used safely.
User-defined functions can now be made to support 'stack lift disable' properly. This is automatic with FUNC, and supported by CSLD? for other functions.

Fixed parameter bounds check in PIXEL.

What's New:

INPUT would crash if R/S was pressed while the stack was empty, in NSTK mode. Fixed.

Decimal version: In HMS+ and HMS-, fixed handling of cases where either or both of the arguments has a number of minutes or seconds >= 60. (The binary version did not have this bug.)

What's New:

Fixed crash in RTNERR when switching back to NSTK mode after FUNC/L4STK.
Fixed ASSIGN "" in programs.
Added PRREG to the PRINT menu.
NN→S now ignores the display mode and always acts like ALL mode is active. The idea being that if you care about the display mode, you'll probably be using N→S, and you only need NN→S if you specifically want to see full internal precision.

Size: 7.34 MB

What's New:

EDIT, EDITN, and INDEX now support lists, acting like they are 1-column matrices. (Empty lists are not supported yet, they must have at least one element.)
Added PRREG. Because PRV "REGS" is not a good substitute.
Added NN→S. This works like N→S, but without the 12-digit mantissa length limit, so you get full precision in ALL mode.
Fixed stack lift handling in DELR and STOFLAG.
Fixed pasting 1/X, 10^X, and 4STK, when pasted without line number and with trailing space.

What's New:

SOLVE does a better job of reporting Sign Reversal when a function changes sign around a vertical asymptote, instead of reporting it as a root.
BASE: complex numbers displayed in non-decimal bases in some cases.
Better OCTM handling in SHOW.
Fixed number entry in PRGM mode when BINM/OCTM/HEXM active.
No longer setting flag 22 if number entry ends with DROP in NSTK mode.

What's New:

Localized Copy & Paste.
More accurate complex ACOS and ACOSH.
SOLVE now handles functions that are always positive or always negative a bit better, reporting Extremum when the iteration appears to be bouncing around without improving, instead of continuing indefinitely.
Added XVIEW function. This works like AVIEW, except it takes the string from the X register instead of ALPHA, so it avoids the 44-character length limit.
The app now removes itself from the task list if exited using OFF.

What's New:

Implemented LCLV: CLV for local variables only.
RND in ALL mode now rounds like in SCI 11, instead of doing nothing.
HEAD, when applied to a string in a numbered register, would corrupt the string if it was 16 characters long before the call. Fixed.
Y^X accuracy improvements with integer X.
Fixed DUPN 2 in 4STK mode.
Added WIDTH and HEIGHT functions, for forward compatibility with Plus42.
L4STK didn't pad the stack to 4 levels when used without FUNC. Fixed.
