Statements 11
11 -34
Use the RETURN statement to return control to the statement following
the most recently executed GOSUB (page 11 -13). Use one return for each
GOSUB to avoid overflowing the control stack. This means that a
subroutine you call with the GOSUB statement can call another subroutine
with another GOSUB statement.
