Re: conflict between UNDO and LOCAL

Aids for creating "persistent local variables"
with pre-assigned explicit values (or all zero):

LOCLV stores supplied value(s) into local variable(s).

LOCLZ stores zero(s) into local variable(s).

CONT abandons the most recent set.

KILL abandons all.

NDUPN (and other HP49/50 series commands) for HP48 series:

@ value 'name'

@ 'name' or { names }
