Enables error handling and, when a run-time error occurs, directs your
program to either branch to an error-handling routine or resume execution.
 
ON ERROR {GOTO line | RESUME NEXT}
 
    - GOTO line      Branches to the first line of the error-handling
                     routine, specified by a label or line number. To
                     disable error handling, specify GOTO 0.
    - RESUME NEXT    Resumes execution with the statement following the
                     statement that caused the run-time error. Use the ERR
                     function to obtain the error code for the error.
 
    - If ON ERROR isn't used, any run-time error ends your program.
