>
ClrErr
Clears the error status and sets system variable errCode to zero.
The Else clause of the Try...Else...EndTry block should use ClrErr
or PassErr. If the error is to be processed or ignored, use ClrErr. If
what to do with the error is not known, use PassErr to send it to the
next error handler. If there are no more pending Try...Else...EndTry
error handlers, the error dialog box will be displayed as normal.
Note: See also PassErr, page 73, and Try, page 105.
Note for entering the example: In the Calculator application
on the handheld, you can enter multi-line definitions by pressing @
instead of · at the end of each line. On the computer keyboard,
hold down Alt and press Enter.
For an example of ClrErr, See Example 2 under the Try
command, page 105.
