ON ERROR GOTO label

Description:

Description:

ON ERROR GOTO enables error trapping so as to pass control to the first line of an

error-handling routine specified by label if an error occurs during program execution.

• To return control from an error-handling routine to a specified program location, you use

a RESUME statement in the error-handling routine.

• Specification of zero (0) to label disables error trapping.

If ON ERROR GOTO 0 is executed outside the error-handling routine, the occurrence of

any subsequent error displays a regular run-time error code and terminates the

program.

If ON ERROR GOTO 0 is executed inside the error-handling routine, the Interpreter

immediately displays the regular run-time error code and terminates the program.

• You cannot trap errors which may occur during execution of the error-handling routine.

The occurrence of such an error immediately displays a run-time error code and

terminates the program.

• You can use ON ERROR GO TO instead of ON ERROR GOTO.
