I agree. On the few cases that I've run into RETURN TO, I've unprogrammed it.
Part of the purpose of RETURN TO is that MV doesn't have the POP command whereby you can remove one of the GOSUB stack references and 'return to' the prior GOSUB statement. Being one who can use GOTO properly and can mix it with GOSUB and CALL for readable code, I don't use RETURN TO.
