6 character upper case variables
All variables are global
256 byte character fields
9 decimal place numeric fields
Short array names
9999 record length
9999 array elements
254 subroutine maximum
50 files
No Date/Time datatype
No parameter validation

Admittedly, only local storage is an ILE benefit, but I would think that the
slow adoption rate of simple RPG IV has little to do with the "goodness" of
RPG III.  Maybe I'm too narrowly focused on individual programs rather than
an entire application?

I can't imagine cost-justifying an application re-write *solely* to convert
to ILE technology, whether the legacy application is good or not.  But if
"...the higher ups are talking about doing a rewrite of our system...", then
I find it difficult to justify deliberately using hobbled technology when
we've already paid for the good stuff.

I personally have implemented new ILE modules/programs/service programs that
are modifications of existing OPM programs.  Thusly creating a mixed
environment for this application.  My mods are somewhat isolated, and I was
able to roll them out as a unit, not disturbing the overall application.  Do
you think this is unusual?  I mean, do you think it would be very difficult
to gradually deploy ILE portions as modifications are made to legacy
applications in your company?

Your note is definitely food for thought.
