Hello!

In HP48, a similar problem was the command PURG closest to the comand EDIT.

It is no longer on HP50 keyboard

Stay tunned!

Every time I accidently rewrite a variable using [LS] [soft key], I recover it by using [LS] [ANS]. It recalls the prior contents of the variable and the variable name onto the stack. Then I simply press STO to restore that variables to its original state.

Only downfall with this method is once ANS/LASTARG is rewritten, the user cannot restore the variable to its original state.

Maybe writing a program to store contents of LASTARG when rewriting variables holding programs, lists, array, etc could be useful. Sounds good on paper at least.

I didn't know this method to recover variables up to now. I plan to save the previuos value with the backup option, beyond Yes or no, at user's command.

If possível, try what I have proposed up to now and ser if there would be any inconvenience. I believe, today, reading The user manual, there will be issues with SOLVE, as I had with Units and Convert.
Best regards and thanks your kind words
