ON to GOSUB
Executes the subroutine specified by the <
expression
> value
Format
ON expression GOSUB label 1, label 2...
* GOSUB can also be expressed as "GO SUB".
Values
expression
..............................Expression whose result is 0 or positive integer
Explanation
The <
expression
> value determines the program's jump destination.
An <
expression
> value of "1" specifies a jump to <
label 1
>, "2" specifies a jump to
<
label 2
>, etc.
Likewise, (<
expression
> value "n" specifies a jump to <
label n
>.)
If the <
expression
> value is "0" or if the <
expression
> value exceeds the number of
existing labels, no jump occurs, and the next command is executed.
After executing a jump destination subroutine, the next command after the ON to
GOSUB statement is executed.
