68 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.
