Subject: macbook air and keyboard emulation
Hello Mac users...
I am using macbook to connect to our (and client's) mainframes. I do not want
to change the keyboard map in the emulation product. what is the keyboard
mapping for enter, ph11 and pf12?

I am using several of them... PCOMM, x3270, Rumba and more. It depends on what
the client is using. The idea is to have a script that match the mac keyboard
with PC keyboard.

Hi
How does the product license key works. Which program determines the
expiration of a product.
This is a general question.

Subject: Re: macbook air and keyboard emulation
That’s completely up to the emulator software to decide. There is no reference
standard since Apple has used so many different physical keyboard layouts over
the years. Just imagine what it would look like on a keyboard configured for
Mandarin, and you start to get the picture. Or for a user with only a Braille
screen reader. Awkward.
If you’re documenting it, use the 3270 function name and say press whatever key
implements that function. It’s pretty much all you can do.

This is a program a vendor develop to protect his ip. It can be cpu serial
limited, model or time. If your interest is time, just compare machine time
with a value in your program. Stck (or $stck macro) will store the clock value.

Subject: Re: Product license key program
As far as I know each vendor has their own process for determining when a
product will no longer function on a given LPAR. The function could be a key
with a date/time in it. They could rely on the customer to renew and then they
get a new key. If not, then the product could expire but continue to work. Or
the product may just stop working. Each vendor has their own requirements on
License keys.
I do not think you will find one specific way they all do it. They realize
there are cleaver people who want to run their software without renewing or
paying. So they work very hard to make sure it is very unlikely anyone can
crack their logic that drives their product authorization process. They may
all grab the clock, but how they use that to determine usage, is probably
proprietary.
Each vendor probably provides a process to see when the product will expire.
There are no easy work arounds when vendors have keys that dictate when the
product will stop working.
Some vendors grab the clock at start up, then store it into some area of their
code where you can not see it or alter it. Then use a key to see where the
clock is and validate the product is still licensed to run.
For example, SAS, provides me a SAS key. I can see the expiration date they
are setting. I cannot change that. The SAS software is very smart and if I
change to a new year without the appropriate payment and secret code to go with
it, it will not work. The SAS license key is added to something else in the
SAS software and that is not visible to me. So if it is 1 day to expiration.
At day 0 the software stops working. But they do give you a 60 and 45 day
warning.
Some vendors will allow you to continue running so long as an IPL does not
occur. If it does and the product is expired, then it will not be available
after the IPL.
Some vendors allow for a Disaster Recovery Key. One that can run during DR
Testing or actual DR.

Subject: Re: Product license key program
As the author of such software, let me confirm what others have said: each
vendor does things its own way -- or perhaps not at all. CA has a central
"server" program for administering licenses; the software I am responsible for
has the licensing embedded in the program itself.
The exact technology is proprietary and a trade secret. To say "we do X and Y
and Z" would be to facilitate its defeat by a dishonest customer.
[And please, let's not start the whole "to key or not to key" discussion again.
Vendor keys are a fact of life. Yes, they can be a PITA. Most customers are
honest -- beyond honest to the point of paranoia -- but a few are not. And
honest customers sometimes make honest mistakes.]

If the timer unit was defined as the same unit as the System 360 timer word,
13.02083 microseconds, where bit 23 is 1/300 second, then 24 hours (86,400
billion microseconds) would be about 6.6 billion timer units which is too large
for a 32-bit unsigned number.
If a timer unit is defined as double the System 360 timer unit, 26.04166
microseconds, then 24 hours of timer units would be about 3.3 billion timer
units, which fits in a 32-bit unsigned number.
I think that's the reason why the timer unit is not the same as the System 360
timer word unit. The 360 timer word unit could not represent 24 hours in 32
bits.
What got me thinking about that was an October 2014 post by you, Tony, where
you said "Possibly they wanted to be able to represent more than the 7.7ish
hours that the positive number range of the architected format provides."
