Updated At: 2023-11-15
Changes: Nov 15, 2023
Version 3.1
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 user-defined functions can use functions like CLST and R↓ without causing side effects.
User-defined functions can now be made to support 'stack lift disable' properly. For functions using FUNC, this happens automatically, and other functions can use the new CSLD? function (Caller's Stack Lift Disabled?).
FNRM and UVEC, when called with very large parameters, could get incorrect results due to overflows in intermediaries. Fixed.
Fixed parameter bounds check in PIXEL.
Added option to use the shake gesture to do CLST in RUN mode.
