ON-GOSUB - Flow Control
Function
Call subroutine beginning at one of several possible line numbers
Syntax
ON expression GOSUB line number, line number
See Also
ON GOTO
Usage
expression selects the beginning line number for a subroutine call. If expression
evaluates to zero then execution continues at the program line specified by the first line
number in the list. After a RETURN statement is executed in the subroutine, execution
resumes with the statement following the ON-GOSUB.
If the value of expression is greater than or equal to the number of line numbers in the
list, then the BAD SYNTAX error message will be generated.
