Type Constant (read-only)
Syntax ON
Description The ON constant returns the numerical value 1.
Arguments N/A
Example OP (lever,ON)
The above line sets the output named lever to ON.

Type Program control command
Syntax ON expression GOSUB label { , label }
Description The ON..GOSUB and ON..GOTO structures enable a conditional jump. The
integer expression is used to select a label from the list. If the expression has
value 1 the first label is used, for value 2 then the second label is used, and
so on. Once the label is selected, subroutine GOSUB jump to that label is
performed.
Note: If the expression is not valid, no jump is performed.
Arguments • expression
Any valid BASIC expression.
• label
Any valid label in the program.
Example REPEAT
GET#5,char
UNTIL 1<=char and char<=3
ON char GOSUB mover, stopper, change
See also GOSUB..RETURN, GOTO.
Type Program control command
Syntax ON expression GOTO label[,label[,...]]
Description The expression is evaluated and then the integer part is used to select a label
from the list. If the expression has the value 1 then the first label is used, 2
then the second label is used, and so on. If the value of the expression is less
than 1 or greater than the number of labels then an error occurs. Once the
label is selected, subroutine GOTO jump to that label is performed.
Arguments • expression
Any valid BASIC expression.
• label
Any valid label in the program.
Example REPEAT
GET #1,char
UNTIL 1<=char and char<=3
ON char GOTO mover,stopper,change
