back on track.
Lesson 38; Error Messages
The HP 48 indicates that it can't do sometliing by sounding a beep
(if the beeper is enabled) and displaying a error message. A complete
list of these messages and their meanings can be found in Appendix

(or any other key).
Here are tlie meanings of four of the more common error messages:
Type. You tried to do something to or with an object
that isn’t valid for that kind of operation. For exam]de, dividing by a
text string causes this error.
Too f s . You tried to do something without, supplying
the calculator with enough stack arguments. For example, executing
(TjT) with only one number on the stack causes this error.
Inual id Card Data. The HP 48 cannot read data stored on a
plug-in card you inserted . However, you will also see this message
whenever a RAM card contains ports you’ve never used. Press
Q P I N I T to initialize all available RAM ports. This
does not affect data already stored on the card.
Undet ined Hane. The HP 48 attempted to execute a command that
recpiires numeric arguments and found a symbolic argument it could
not convert into a number. If the command
s h o u l d
accept symbolic
arguments, then perhaps the Numeric Results flag (-3) is set (press
(f^ F'LflG to check). Clear it and try again.
