Todd,
It would be true to say that "Red cars can be used for traveling". However, it
would be misleading to say that because the color of the car has nothing to do
with it.
In the same way, it is true to say "When you use the Dialog Tag Language, you
can define a field as point and shoot". B

"FYI: Point-and-shoot has nothing to do with Dialog Tag Language."
Nothing, of course, other than being an exact term and concept used by IBM
for describing a facility of the ISPF Dialog Tag Language?

Not true. If you code a DCB macro without a BLKSIZE, the blocksize field in
the DCB is left as zero. That is not the same as specifying zero
Hi Todd
Thank you for your answer
The "REPORT VIEW/BROWSE" would be o.k, but for the LEDATA report I get
only a part of the list.

wanted to have.

Kees, Ted, Terry,
thanks very much for your reply. I first looked at 'z/OS 1.9 DSMS Using Data
Sets',
but could not find such a direct statement. I wil

If you use BLKSIZE=0 in your JCL you should be achieving that.
BLKSIZE=0 is *not enough* for tapes (in general).
See BLKSZLIM in DD and DEVSUP parameter. Last, but not least is the

Hi Walter,
With regard to "are you saying that the application program which actually
writes the tape has the last word to decide how to block the dataset on
tape?"
Historically DCB information has been acquired via the Open/Merge process
which applies to data sets irrespective of them being tape

My first question would be what do your WLM definitions look like? It
might not make much difference if you have lots of extra capacity, but
if you are constrained, even for relatively short periods of time (which
may be difficult to detect with RMF), a good or bad WLM policy can make
a big dif
