Hi, HP71B users;
my turn to ask questions.
I received one e-message mentioning the HP71B's ROM version. How can I know which version is mine? Serial # or some specific command?
I remember that BASIC variables are all set to "0" (empty?) and all definable variables for an specific BASIC environment exist anytime a program "call" their contents. This is not the same with C, where variables not "declared" in a program are taken as "error" if called. Anyway, based on what I saw so far, used variables in the HP71B consume memory space. Is there a way to list varable names already used somehow?
Thanks for any help.
