Convert Upper case to lower case in a CL

Ravi,

Here is a sample of converting one paramter to lowercase using the
current CCSID of the requesting job.  The one value that would need
changing is &DATASIZE and the LEN() of &PARM1 -- these two must match
and represent the size of the variable to lowercase.

To handle three input parameters simply vary the second and fourth
parameters being passed to QLGCNVCS (Convert Case).

             PGM        PARM(&PARM1)
             DCL        VAR(&PARM1) TYPE(*CHAR) LEN(10)
             DCL        VAR(&REQCTLBLK) TYPE(*CHAR) LEN(22) +
                          VALUE(X'00000001000000000000000100000000000+
                          000000000') /* Use Job CCSID to convert +
                          input data to lowercase */
             DCL        VAR(&DATASIZE) TYPE(*DEC) LEN(2 0) VALUE(10)
             DCL        VAR(&DATALEN) TYPE(*CHAR) LEN(4)
             CHGVAR     %BINARY(&DATALEN) VALUE(&DATASIZE)
             CALL       PGM(QLGCNVCS) PARM(&REQCTLBLK &PARM1 +
                          &PARM1 &DATALEN 0)
             ENDPGM

If you are interested in the specifics of this API call, see the
National Language Support APIs in the System API Reference.
