Paul:
I was interested in Skips item.
I was thinking about it after I read it and (I did not come up with
the share codes like you did) thought it as an idea (not sure yet if
its good or bad).
The slight problem I could foresee is that a vendor might come up
with their on "code" that conflicted with a company standard and then
the fun begins.
I haven't decided whether its a good/bad idea (yet) but it is
something to think about (thanks Skip).

Good catch. In my recent SHARE pitch on system symbols, I strongly

that all such symbols be prefixed with an installation

as SHARE company code, to clearly identify them as user defined. This
practice will also group installation symbols together in a D SYMBOLS
display.
Where are the SHARE company codes listed? What is their domain of
applicability? Do these exist in parallel and in contention with IBM
registered component prefixes.
In a universe with less archaic length restrictions, the custom is
to incorporate
a registered domain name, rewritten big-endian. IBM shows some slight
adherence to this in such as:
/usr/lpp/booksrv/cgi-bin/com.ibm.bkmgr.CgiJavaBridge.jar
/usr/lpp/smp/classes/com/ibm/smp/GIMJVCLT.class
What!? not "com.IBM"?
I surely wish SMP/E SYSMOD IDs were so flexible that we could
incorporate a corporate ID (preferably domain name) in PTF
names.

No. As documented, "The length of the resolved substitution text
cannot
exceed the length of &symbol, including the ampersand on &symbol and
excluding the single quotation marks on 'sub-text'."
So your example is not valid.
An abomination; it ain't that hard to code a routine that substitutes
values longer than their names. Doesn't that work for JCL symbols?
But they can *never*fix*it* if, as I assume, the symbol substituting
facility has no way to report a buffer overflow, and (some) callers
are
in no position to handle an error if one were reported.
