RE: QSYSINC/QUSLFLD usage in RPG in V5R2

Yes, but then the service program may not work because you recompile it and
miss a subtle change that IBM made on the new release.
I recommend _only_ using /COPY and /INCLUDE for API data structures; whether
or not you've made your own copies of the QSYSINC library.
Granted the QSYSINC /COPY members are in an "I don't know RPG" syntax
converted to RPG IV from C using a software tool, and granted the field
names suck, and granted the data structures should use the QUALIFIED keyword
today, and granted the integer fields should all be 10i0 instead of "B", at
least they are updated on each release.  :)

You could, of course, also physically copy the source into your program
(instead of doing a /copy).  While I really like /copy for prototypes
and constants, I don't frequently put Datastructures into /copy
members.  

I suppose I'll get beat up because this isn't very modular-ish, but I
like to have the actual definitions right in my source code. Had this
been the case, the program would not have ceased functioning... Of
course, I also only have one copy of this DS because I encapsulated the
API functionality into a single service program.
