Implement full RPN

Is it possible to tread the command line like a stack level? i.e. swap a value on cmd witk stack 0?

by Angus

Spreadsheet input should support this too, right now event the basic entry with spaces fails

by Erwin Ried

HPPPL is not suited to stack interaction like RPL & key stroke progamming were.

7
HPPPL could be extended by methods to access Home stack.

by robocop

2
Stack or commandline content can be treated as input parameter list for HPPPL routines.

by robocop

3
Then RPL interpreter(or compiler) too! Throw out current dumb stuffing, it makes this calc pathetic.

by Xsetset

2
RPN is not only convenient input method, it also gives working area in stack levels (temp variables)

My apologies- in my enthusiasm I voted 2 times for this idea.

xCas only accepts algebraic notation, so full RPN integration wouldn't mesh as well as it does now.

Make this available via keyboard shortcuts, e.g. On+Z (undo), On+Y (redo).

consider performance tradeoffs. Objects vary in type and size. purge(spreadsheet|notes|ap...)->undo?

by Angus

2
With a good implementation the tradeoff is minimal, mostly memory

by Erwin Ried

Hint: Use difference, no need to save full prev state. Others solved this task.
