Errors and error trapping
The functions of the PRG/ERROR sub-menu provide ways to manipulate errors
in the calculator, and trap errors in programs. The PRG/ERROR sub-menu,
available through
„°LL
@)ERROR@
, contains the following functions
and sub-menus:
DOERR
This function executes an user-define error, thus causing the calculator to
behave as if that particular error has occurred. The function can take as
argument either an integer number, a binary integer number, an error
message, or the number zero (0). For example, in RPN mode, entering
5`
@DOERR
, produces the following error message:
Error: Memory Clear
If you enter #11h
`
@DOERR
, produces the following message:
Error:
Undefined FPTR Name
If you enter “TRY AGAIN”
`
@DOERR
, produces the following message:
TRY
AGAIN
Finally,
0`
@DOERR
, produces the message:
Interrupted
ERRN
This function returns a number representing the most recent error. For
example, if you try
0Y$
@ERRN
, you get the number #305h. This is the
binary integer representing the error:
