GOSUB ~ RETURN
Format
GOSUB {<line number >
<label>
RETURN
Abbreviated Format
Explanation
GOS. ~ RE.
The GOSUB statement transfers program control to a subroutine identified with
<label> or beginning at the line number specified in <line number>. After the
subroutine has been executed, control is returned by the RETURN statement to the
line following the GOSUB statement.
A subroutine is a set of statements that may be used more than once in a program.
One subroutine may call another subroutine which may call still another subrou-
tine. Nesting of such subroutines is limited only by the available memory space.
Each called subroutine must have a RETURN statement at the end.
