Anyone,
I'm just getting familiar with the RACROUTE macro. I have a working example
of the macro with REQUEST=AUTH that generates a violation when
appropriate.
My question is: is there a way to interrogate RACF (presumably via the
RACROUTE macro) to simply *ask* whether or not a particular
Another way is to issue a RACROUTE REQUEST=EXTRACT
LOG=NONE
Am I correct when I say that both of these solutions require APF-authorization
(or similar)? Might there be a way that would not require this?
I wouldn't have thought that there would be a security issue with merely
interrogating an
For your own userid, you can use LISTDSD or RLIST to check resource
authorization without cutting audit records.
That would be perfect... is LISTDSD something I can do from within an
assembler program? Or is there an assembler macro equivalent?
All I really need to do is, from within an
All I really need to do is, from within an assembler application, invoke some
function that will tell me whether or not the current userid is authorized via
a
given RACF profile to *read* a resource. The userid will always be either the
person who is logged onto TSO or is the submitter of a
If the user has given you a data set name and asked you to operate on it,
and he does not have the proper authority, then it is most appropriate to
have the violation occur.
Not in this case, IMO.
The violations are occurring as a result of a text string scan across all
members of a

Yikes!
Our programmers occasionally ZAP a load module in a test load library, which is
fine. When the time comes to promote the load module into a production load
library, however, I would like our change
You can browse the load module and see IDRDATA if you know what to look

I think I might start with that approach. I have the documentation.
Thanks so much, everyone, for all of your rapid and informative responses!

Anyone,
I have a mainframe assembler application which is invoking Unix system
services to get the names of all of the files in an NFS-mounted folder. The
application dynamically allocates and logically concatenates these files into
one giant dataset, then uses QSAM macros to read it.
The

number of allocated DDs and devices. Deallocate data sets that are
Yes, it is a bit more difficult to program, but it is infinitely scalable.
Of course, you are correct. I took this approach because I have inherited a
pre-existing application that used to read a single mainframe dataset. It's

Just tried it; no good. Same result as before. Thanks, though.

No apologies necessary!

I'm working with a skeleton that generates an EXEC statement that looks like
this:

is 8 characters long, the trailing blanks from the ZUSER variable are

Wilkie's earlier post).
Thanks, gentlemen.

If you have other parms at fixed offsets, then this won't work.
I don't have other parms right now, but I would like to reserve the right to do
so going forward. That's why I was hoping to force the length of the PARM
string to 8.

Anyone,
I'm an application programmer. We are on z/OS 1.7. If I wish to see the
system ENQ status of all ENQs for a given major name, I do this within
ISRDDN, option ENQ. I filter on the major name prefix, and I see all the ENQs;
voila. However, if the *entire* minor name doesn't fit on the
Is there a way *YOU* (as an application programmer) can do it
Of course I can, if I have to. The ISGQUERY macro provides all the info I need.
My point was that the precise tool that I need is already available in ISRDDN,
but unfortunately, the piece of the rname that I need to see is just
At the side of the dsn type the command ISRDDN E
It's not a dataset that has the enqueue. It's an application program (CA's
PanAPT) that has done an ENQ on a resource with an 84-byte minor name,
and I need to see the entire rname to know who has the enqueue.
I've coded my way out of this by
Anyone,
Is there a way for an executing assembler program to extract its own load
module name for programmatic examination? (If it matters, it would be the
original load module called via an EXEC statement in the JCL; it wouldn't have
been loaded by a previously executing program.)
Thanks so
Thanks, everyone. Someone e-mailed me with a beautiful solution. I coded
this:
L RF,PSATOLD-PSA(,0)
L RF,TCBJSTCB-TCB(,RF)

Follow up to my original post: the ampersands seem to have nailed me even in

the CLIST should produce

I.e., two ampersand characters concatenated to the relevant string (e.g.,
So, as you want 2 ampersands you need to use 4, and thus I suggest trying:

Anyone,
I'm a newbie with IEBUPDTE, which I'm using to add members to a temporary
PDS for use in a later job step.
I checked the manual, but I can't seem to find a way to add
comments/remarks to the IEBUPDTE SYSIN input. Is there a way to do that?
Thanks so much.
David
Utility control cards adhere to the JCL/Assembler standard
allowing comments on the control cards after the last operand,
and with one or more separating spaces. If that's not enough
room, you're out of luck.
If you're updating to a temporary, why not include comments in
the contents, appropriate
the closest you'll come to that is to put a flower box (why tombstone?) as
comments preceding the SYSIN (using //* comments), or adding a dummy
member
Ah, so. Got it. Thanks so much for your help!
