Re: CL: Numeric padding

[Rob Berendt <robertowenberendt@xxxxxxxxx>]

As much as I'd like to promote BRMS and having meaningful tape names is
long dead I suspect that's not an option for your shop.  So try this:
DCL        VAR(&JOBDATE) TYPE(*CHAR) LEN(6)
DCL        VAR(&YYMMDD) TYPE(*CHAR) LEN(6)
RTVJOBA    DATE(&JOBDATE)
CHGVAR     VAR(&YYMMDD) VALUE(%sst(&jobdate 5 2) *cat +
             %sst(&jobdate 1 4))
SNDMSG     MSG(&YYMMDD) TOUSR(ROB)
