Hi Reggie -

The CPP source:
 RTVSTRLEN:  PGM        PARM(&STRING &STRLEN)
             DCL        VAR(&STRING) TYPE(*CHAR) LEN(5002)
             DCL        VAR(&STRLENA) TYPE(*CHAR) LEN(2)
             DCL        VAR(&STRLEN) TYPE(*DEC) LEN(4 0)

             CHGVAR     VAR(&STRLENA) VALUE(%SST(&STRING 1 2))
             CHGVAR     VAR(&STRLEN) VALUE(%BIN(&STRLENA))

You can simplify this by defining &STRING with a length of two and not using &STRLENA. Since the caller owns the storage, there is no need to define it any longer than what you need to use.


If you really want to keep the length of &STRING matching the command definition, you can still eliminate &STRLENA since %BIN accepts a starting position and length parameter:

CHGVAR VAR(&STRLEN) VALUE(%BIN(&STRLENA 1 2))
