ERR

Similar to ERL, except ERR returns a value related to the code of the error rather than the line in which the

error occurred. Commonly used inside an error handling routine accessed by an ON ERROR GOTO

statement.

ERR/2+1 = true error code (true error code -1)*2=ERR

Example Program

10 ON ERROR GOTO 1000

20 DIM A(15): I=1

30 READ A(1)

40 I=I+1: GOTO 30

50 REM REST OF PROGRAM

100 DATA 2,3,5,7,1,13

999 END

1000 IF ERR/2+1=4 RESUME 50

1010 ON ERROR GOTO 0

Note line 1000: 4 is the error code for Out of Data.

1 2 ... 24 25 26 27 28 29 30
