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.
13
 
HPPPL could be extended by methods to access Home stack.
by robocop

Stack or commandline content can be treated as input parameter list for HPPPL routines.
by robocop
6
 
Then RPL interpreter(or compiler) too! Throw out current dumb stuffing, it makes this calc pathetic.
by Xsetset

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

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.
by iconmaster

It might be sufficient, if the stack is a global variable that we can manipulate with HPPPL.

Agreed, Robert Graulich. For details of #RPL as an Application with Lists T0..9 search "Nousiainen"

Implement UNDO-REDO
by Erwin Ried
All actions, or at least the editors really need undo and redo actions!
 
Make this available via keyboard shortcuts, e.g. On+Z (undo), On+Y (redo).
by Stefan

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

With a good implementation the tradeoff is minimal, mostly memory

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