GOSUB

Changes the normal downward flow of control.

Syntax

GOSUB x

Parameter

x	any valid numeric expression

Remark

This command is like GOTO, except control may be returned to the statement following the GOSUB by executing a RETURN statement.

Example

GOSUB	1000
	100	REM Return Here
	.
	.
	1000	PRINT B
	1010	RETURN

In this example, control is returned to line 100.
