QMF Batch - maximum length for passed parameters ?

[twolights58]

I am able to run QMF in batch mode from a JCL member including
passing parameters via the //SYSTSIN card to be received
as QMF variables. See below example, where &&US, &&S1, &&S2, and &&S3
are four parameters being passed to QMF procedure: abcd.QMF_TB_MFX_P1 to
be received as QMF variables.

/RUNQMF30.SYSTSIN DD *
ISPSTART PGM(DSQQMFE) -
PARM(S=DBX0,M=B,I=abcd.QMF_TB_MFX_P1 -
(&&US='ABCDEFG',&&S1='1111111111',&&S2='222222222',&&S3='333333333'))

The problem that I am encountering is that there appears to be a limit similar
to the JCL PARM statement, of 98 bytes (give or take two bytes). Furthermore,
the number of bytes that add up to this limit include everything in the
above example beginning with S=DBX0 and ending with &&S3='333333333'.
In other words, certain non-negotiable items such as the DB2 subsystem and
QMF procedure identifiers are included in these 98 bytes; so that limits
the number of parameters that can be passed to be used as QMF variables.

I guess this limit may be tied to the IKJEFT1* TSO batch program and not
QMF batch per-say. In any event, is there away around this limit ?

thank-you kindly
