It's not that clear-cut. Some developers provide better support for
free software than other developers provide for chargeable software.
I've gotten excellent support for free software, including some from
the CBT. The Devil is in the details.

I'm correct about suggesting LEFT as an alternative to SUBSTR in REXX.
However, Peter is correct about SUBSTR not working the same in PL/I as
in REXX, at least when STRINGRANGE is enabled.

Try test = 'abc' (if varyying), or declare test as CHAR(3).

Is it legal for you to download .net without owning a windoze license

If your bonuses are based on 90 day cash flow, what are you going to
optimise? As long as corporate decisions are driven by short term
fluctuations in the stock prices, you are going to see decisions with
adverse long-term consequences.

There is none. A DSCB is an entry in a VTOC on DASD.

There is no "of course'; the fact that you can mount the volume at a
later point in time does not mean that it was mounted when you did the
I line command.

Which has nothing to do with whether the tape was mounted before your

Not for accessing a tape label. It is useful of you want to
dynamically select a file from the tape.

>but would be grateful for any suggestions.

There are many tape scan programs on the CBT. If you have BLP
authority then you could read the tape labels yourself. You could also
write a program to OPEN a tape dataset for input and examine the DCB
parameters merged into your DCB.

SC26-7410-09, the 1.11 version of DFSMS Using Data Sets, still gives

Not even close. A BIF is a function that the compiler recognizes;
adding a routine to a link or run time library does not make it a BIF.
Frequently, but not always[1], the compiler will generate inline code
for a BIF.

[1] E.g., not for evry BIF or not for every use of a specific BIF.

You already got an explanation of LPAR and TPF. Note that Airline
Control Program (ACP) is the OS for TPF. This is an appropriate venue
to discuss the IBM software, but probably not airline and bank
software running under TPF or the specifics of a customer-vendor
dispute.

>In short it mostly seems to "be IBM".  Recent statements by the

They might be telling the truth, but they have an incentive to make
the claim even if it's false.

>I've love to see IBM follow that up with a statement in the manner 
>of "Stop using our code or be  subject to legal penalties".

I doubt that there's a contractual basis for yanking the license. Even
if IBM sued for libel and prevailed, I'm confident that they'd have to
continue licensing z/TPF on the same terms as for other customers.

>Is Pars or Ipars an actual operating system?

PARS is an application running under ACP. An LPAR is a virtual machine
managed by the PR/SM feature of an IBM processor, which started as the
CP component of VM.

It may not be the student text I'm thinking of, although the date is
in the right era. The one that I'm thinking of was around for several
years and "simplified" the explanation in PoOps by claiming that the
instructions only operated on decimal data. That made it hard for them
to understand the code for translating between binary and hex.

The 305 RAMAC had a disk drive long before the 7090. It's conceivable

such a claim.

Never needed, or never found it useful when available? I wrote XEDIT
macros to automate entry and indentation of common control structures,
and they definitely improved productivity. Similarly, ISPF templates
can speed up coding.

Now, none of those come close to a syntax-directed editor, much less a
full IDE, but they still improved productivity.

>What is the most current register values   TCBGRS or RBREGS

That depends. RBREGS reflects register contents when the program or
SVC was called; TCBREGS reflects the most recent register contents for
the task. If you're taking a dump then TCBREGS for the dumping task
will reflect the operation of ABDUMP or ABEND, which is not likely to
be of interest to you.

>I Know it depends where the code is executing for example if it

RBREGS is not the *current* register contents.

Unless it's looping in an SRB, Type 1 SVC or Type 6 SVC. Also, see the
note above about the dumping task.

That's a different question, because you don't have extraneous SVRB's
complicating the situation; RBOPSW and TCBGRS.

How do you know that the SVC 107 was actually invoked?

That depends on the rule being broken. For issuing an SVC, it's an
ABEND.

CBT tape.

S0C1 is an ABEND code, not a program check. What happens with a
program check depends on the specific interrupt code. For those
leading to an ABEND, the behavior depends on your recovery
environment; normally you will have, e.g., an FRR.

Yes. If you can find suitable contacts in the UNIX® community[1],

Nonsense. There are lots of reasons that a system still has known
security holes, and the reasons are rarely technical, at least not
since the advent of MVS. If you become aware of a security exposure,
get management signoff and close it.

Don't confuse load modules with program objects. The BINDER will only
create a load module in a PDS and will only create a program object in
a PDSE. The formats are pretty much unrelated. I'm not aware of any
new load module features added by the BINDER; in particular, there are
no long names and no classes, hence the need for the output of newer
compilers to go into program objects.

No. A program object is an old[1] style executable module[2] that is
the output  from the binder when creating an executable module in a
PDSE. What is new with V5.1 is that the creation of load modules in a
PDS is no longer supported.

[1] But not as old as a load module.

[2] Unrelated to GOFF, which is the format for object modules

It's not the use of GOFF per se that requires program objects, it's
the use of GOFF features that aren't supported in load modules.

A drum *is* real memory. In this case, 2K 10 digit words.

If your RAM is in a centrifuge.

Every drum computer that I know of had a head per track, so access

Just for IBM mainframe their were a variety of IBM and Teletype®
terminals in common use. I believe that the 2741 was the most popular.


>Has anyone typed TSO or compiled programs

Not I, at least not on an IBM system. I may have done so for a UNIVAC
1230, but, if so, I've gratefully forgotten.

>What was it like to work on a key-punch

Better than handing coding sheets to a keypunch operator and
correcting her errors; not as good as using an online text editor.

>I suppose, 3278 terminals were introduced much later by IBM.

Yes, but the 3277 was available much earlier, in 1971.
