MICROFORUM

I have tested on my 9825A: 25 -> p1 and got error A5. My 9825A has General I/O - Extended I/O ROM, Matrix ROM and String - Adv. Programming ROM. The 4th ROM slot is empty. Maybe another ROM is needed. The p-variables exists. I have found two old reports (one from NASA) with description of p-variables.

That is Interesting information, but I wanted to emphasize that I couldn't find anywhere in the HP-85 user documentation that "they don't allow a quoted CR character" [specifically, a typed Ctrl-M being a CR character in a quoted string]. Also as demonstrated, it appears that it works fine...
