Re: CL: Numeric padding

[Scott Klement <midrange-l@xxxxxxxxxxxxxxxx>]

FWIW... this is how I typically do it:

PGM

    DCL VAR(&SYSDATE) TYPE(*CHAR) LEN(6)
    DCL VAR(&TAPLBL)  TYPE(*CHAR) LEN(6)

    RTVSYSVAL SYSVAL(QDATE) RTNVAR(&SYSDATE)
    CVTDAT DATE(&SYSDATE)  FROMFMT(*SYSVAL) +
           TOVAR(&TAPLBL)  TOFMT(*YMD) TOSEP(*NONE)

ENDPGM
