ERROR( ) Function
Returns the error number for the error that triggered an ON ERROR routine.
ERROR( )
Return Value
Numeric
Remarks
ERROR( ) returns the number of the most recent error. An ON ERROR routine must be active for ERROR( ) to return a value other than 0.
When an error is trapped during program execution, the error type can be returned by ERROR( ) in an ON ERROR routine. The corresponding error message can be returned by MESSAGE( ).
The value ERROR( ) returns is reset by RETURN or RETRY.
Example
The following example demonstrates a simple error-handling routine that displays a message when an error occurs.
CLEAR
ON ERROR DO errhand WITH ERROR( ), MESSAGE( )
*** The next line generates an error - there is no BRWSE command
BRWSE
ON ERROR
RETURN
** Error handler **
PROCEDURE errhand
PARAMETER errnum,message
? Message
? 'Error number: '+ ALLTRIM(STR(Errnum))
RETURN
