ON ERROR

The
ON ERROR
command can be used to prevent a program from halting in the event of an error. If an error occurs in a previous line during program execution, the
ON ERROR
statement calls the
GOTO
or
GOSUB
statement and allows the program to continue.
Format
ON ERROR GOTO <A>
ON ERROR GOSUB <A>
Parameters
<A>
= the destination location in the program should an error be triggered on the previous line.
Example
This is an example of how to use the ON ERROR command:
30 LET A = B/C 40 ON ERROR GOTO 100 ... 100 PRINT "DIVIDE BY ZERO OCCURRED" 110 LET A = 0 120 GOTO 50 ...
Comments
If there is no error, this line is ignored.
This is a program command that is preceded by a line number.
