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
