Total agreement! What I wish were a possibility would be an totally new
construct with similar semantics to a GDG. But the LLQ would somehow
encode the creation date & time (perhaps to the nearest second). No, I
don't know how to encode that into 8 "printable" characters. The
semantics I would like would be the ability to get the "current", "-1",
and so on entries without knowing the actual LLQ. And the ability to
create a new "generation" symbolically (likeunto the +1). Of course, the
problem is once again, what is the "date & time". Submition, or job
initiation or step initiation or dataset open or ...? Oh, and should the
encoding be for local time or GMT? OK, it's a stupid idea.
--------------------------------<unsnip>------------------------------
Not such a stupid idea at all. At Clearing, we "archived" huge numbers
of small reports every day. We developed a routine that incorporated the
last 6 bytes of the TOD clock into the DSNAME, as the last two
qualifiers. The dataset was ultimately created by a subroutine ("DYNAM",
from the CBTTAPE site) that was called by the report generator program.
The actual report name, time and date were entered into a VSAM database,
along with the true DSNAME, and made available to users via a
custom-built search/print program. FDRABR, then later, HSM, managed the
actual reports' location and the VSAM cluster was periodically reorged,
because of the large number of splits even when we used Sequential
Insert Strategy. A relatively simple-minded compression algorithm
reduced the report sizes' by about 70%, on the average. Rather than use
hard-coded values for dsnames, we used the PARMLIB interface, so we
didn't have to re-link anything if we changed any of the "hard-coded"
values.
