HP-50g dangerous L-Shift STO shortcut

[Carsen]

Sounds like a very useful program.

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.
