DAILY changes to your System Values and IBM commands

How about editing your i5/OS system values every day in a controlled,
safe manner.

On your System I, for those system values that you have customized and
those IBM commands that you have changed from default values, I suppose
that you perform those in a CL program that you run regularly, even
daily. Here are a few lines from the CL we run each day.
Will come in handy when we upgrade from i5/OS V5R3 to a more current
release. Won't have to hunt and search for all the custom mods we have
made.

/* World Writer files created will max the file size. */
