als are great for looking up an isolated fact; IMHO, they
leave much to be desired for serious study.

ackups are (1) off-site storage, (2)
multiple PiT recovery, (3) logical error recovery. All this can be done
with disk-only environments involving remote copy and lots of disk space,
but all that becomes expensive for smaller shops.

Thank you all! My old memory seemed to recall something like
DSN=VTOC.FORMAT4 which, while on the right general track, obviously
does not work. Never thought to look in Superzap for the information.

Wow. Everyone is being helpful. I am making a temporary ("one shot")
tool to help with a different problem that might involve dataset locations
on DASD. Was thinking of reading the VTOC directly versus picking fields
out of a IEHLIST DUMP listing. At the moment I am going with the IEHLIST

Unless you are an ISV, a member of the IBM Partnerworld, and eligible for
the z Systems developer discount program, your path would be to zD&T.

You might check "groups.yahoo.com/group/z1090" for zPDT, although I
believe some zD&T users appear there also.

If the "dongle" you mention is for zPDT and you intend to switch this
among several PCs, then you should pay attention to the Linux TOD in the
machines. Remember that the zPDT setup should never see the TOD run
backwards.

For a small project I had almost 30 years ago (definitely a non-IBM
project) I purchased an Overland Tape unit. It was SCSI attached. I also
had a DVD writer attached to the PC and did a fair bit of coding to make
software that would read a 9-track tape and write the data on DVD.
Included were
The long-ago set of programs I wrote to read 9-track tapes on a PC
processed physical tape blocks, in binary, and added a header to each
block before writing it on the CD. Another program could read the CD and
write a new 9-track tape, if needed. My program accepted a double tape
mark to mean e

Not being a COBOL person, I could not resist trying the prime number
COBOL program previously listed. Working on a zPDT system (based on a
rather large laptop) I tried the NA-LINE OCCURS 26214 version and this
took .14 seconds CPU, producing about 2800 lines of output. I then tried
the NA-LINE
Being a bit more curious, I set //GO.SYSOUT DD DUMMY to remove the
overhead of formatting and printing, and the CPU time for the 3355440
version went to 1.10 seconds. Very impressive.

Today, I think one can flip coins to decide on a particular meaning for

You should see in 1+5 in GPR1, 2+6 in GPR 2, etc.
(It works with zPDT.)

G'day Bill,
Is there a typo in your program?
I changed
VL 1,VEC2
to
VL 1,VEC1
and got the expected results.

You are quite correct. My old fingers no longer hit the right keys!

Before saying something like "COBOL is terrible compared to the English
language" try studying a remote analysis of common, everyday English

Before pontificating on "stupid" patents, PLEASE study the general field
just a tiny bit! These are defensive patents and the unfortunate patent
systems (mostly led by the U.S.) make these very necessary. The only
stupidity involved (other than the whole patent process) is not
understanding th
