James,
Wow, does your shop run COPICS?
I have good and bad news for you,
The good news first, LLC is still supported sort off as
of IMS V8.
By support the macro that generates the low level code
checker is still
around and has actually been maintained ... the Macro
name is DFSNN and
the most recent APAR is PQ63275.
Now the bad new, the manual was last reprinted in 1993,
If you have that
one it is most likly the latest. The manual is not
orderable from IBM but
if you need a 'close' copy the DOS version can still be
ordered, last
updated in 1984 DL/I DOS/VS LOW-LEVEL CODE/CONTINUITY
CHECK FEATURE
(SH20-9046-03)
I would suggest you check the IMS applications
programming guide or the
CICS / IMS interface guide ... you might find
something.
For people who might be interested in what this very
very old peice of
code does ... its sort of a carry over from IBMs first
DBMS which was
named at various times BOMP TBOMP and DBOMP the BOMP
stood for "{Bill of
Material Program" I will let you guess what the
letters T and D stood for.
In this system there were a pair of structures called
parts and
assemblies. Assembiles were made up of parts and the
data base was
relational long before DB2. For that matter, long
before the system 360.
When it got converted to IMS which many people thought
was a natural
because of its heiractial structure there was an
exposure of creating a
circular reference betewwn parts and assembiles. LLC
was designed to
check for circular references.
Just for completeness for those who have some interest
in this historical
stuff BOMP actually had 4 relational tables ... Parts
and assemblies
(which we just discussed) and Workstations and
Routings The first pair
were intended for order / inventory and the second
pair were for shop
floor control.
As it happens the DBMS system was used more often for
accounting and
payroll than what it was for manufacturing systems it
was originally
desinged for.
COPICS came out in the mid 70's and it was intended to
upgrade BOMP to the
CICS DLI world. Lots of very fancy publications but I
never heard of
anyone actually getting it to work.
James if you want to discuss this write me at my Email

of this.
