RE: RPGII to RPG IV

Bob -

There are no RPGII programs on the 400.  The compiler creates MI just like
RPGIII.  Only the front end syntax checker is different.  So, you can use CL
and skip the OCL if you want, or you can mix and match.  There are only a
few restrictions when using CL.  The main one being that if you don't use
OCL, you can't create files on the fly (at load time in OCL).  See the
System/36-Compatible RPG User's Guide and Reference for the all the
restrictions.

Also you can compile RPGIII code and run it in the S/36 environment with
OCL.  Again you can mix and match in the S/36 environment.

Yes, but I suppose my concern is how the other programs (still in RPGII)
will react to those files once they are converted. This program is not an
island and the files are used in other areas and other applications.
Thanks

Bob,

  Multi-format LF's work quite well for this purpose.  For input only, you
can create the fields with SST().  But the beast for the long term is
probably to separate out each format into its own PF and use the MFLF as
the glue to bring them all together.  The MFLF would have the same name as
the original PF.
