Yup! The interrupt works fine in NT/2000, but BIT(pbvHost,8) does not return TRUE for NT/2000. You'll need to check that condition separately.

Something *simple* like this works for me:

Code:

IF UCASE$(ENVIRON$("OS")) = "WINDOWS_NT" THEN IsNT% = -1
IF BIT(pbvHost,8) OR IsNT% THEN
...
END IF

The "%" type-specifier tells the compiler the numeric literal value is to be treated as an integer, however, the compiler will interpret the plain 8 as an integer anyway (in this particular context).

In summary, either way works fine, and there is no particular need to use one or the other.

However, in some other circumstances you may prefer to add a type-specifier to a numeric-literal, so that the compiler casts the value to the correct precision.

For example:

Code:

x## = 1.1   ' single-precision value assigned to a extended-precision float
x## = 1.1## ' extended-precision value

Lance ..

For the record on this thread, as well as the other that had a
reference to time slice work:

DOS-VDM's and your suggestions as to how to release time slices
for this sort of thing does work fine for compiled executables
running in DOS-VDM's in OS/2. It is possible to trap and ID
the OS/2 instance and handle it just fine for the 3.5 compiled
executables.

More important, I've been able to find and document something else
that is related to this which ought to be posted in this thread
for the few OS/2 afficiandos here.

The F0 Bug fix code for OS/2 was distributed as a driver file in
the following file:

cmpxchg8.sys 2,634 5-03-99 6:53p

This driver was released as part of FP 6, and would have been
automatically added to your system directories in any fixpack
of this date level or later. With a few rare exceptions, the
fixpacks are cumulative. FP 6 was not widely installed, as I
know it, in comparison to, for example FP 5, or later, especially
until FP 8. FP 8 and FP 9 were perceived to be quite stable and
were installed by a significant number of users, if the published
comment text is any example.

The current FP for Warp 4.0 is now FP 15 .. which would have that
file in it, even if you went directly from no fixes to FP 15.

It is important to note that FP 8 didn't show up until well into the
year 2000, I think. Thus many, many people can have the needed
driver for the system, but be totally un-aware that it is needed,
and isn't installed. OS/2 does have a CPU sniffer for install
purposes, but recall we are still dealing with an OP system which
was introduced in 1996 which is still solidly viable even 5 years
later!

That after what I think is over 30,000 fixes at
removing bugs ...

All code has them.

The mark of excellence is how you handle them
and your attitude about both admitting them,
sharing full disclosure about what they were
and what got fixed.

Virtually all of the MASSIVE amount of work for
every one of these resolved fixes is admitted
in the public database that IBM maintains on
all this.

The dirty linen's most all there .. in contrast
to some organizations which do not post the
whole details.

Like 'em or not you have to respect IBM ..

And Version 3 is STILL working and solid for a lot longer than
1996 as well. I can't be sure, but it seems that as long as
the latest FP 40 for Version 3.0 is in use, the above driver may
perhaps work there too. That's significant, because version 3.0
is still on a lot of boxes which are servers. Curiously, because
of the efficiency of OS/2 (and LINUX), even a 486 server with only
about 64MB of memory makes a fine HTTP, TELNET, FPT and firewall
server as just a throw-away box. Thus many low level boxes are
put into service for things which are cast off's and .. here comes
the older CPU problem with them!

The important thing is that even if that file *IS* on your system.
the driver is *NOT* installed by the fix routines. It must be
added to your CONFIG.SYS file by hand, or by some form of smart
took which can modify your CONFIG.SYS coherently on its own. The
correct line in the CONFIG.SYS file for it is:

BASEDEV=CMPXCHG8.SYS

I've seen it installed right after the TIMER.SYS loader, but the
OS2LDR re-arranges the load order of CONFIG.SYS to suit itself
over what may be a hundred or more lines of goodies (or worse!)
For those of you whom are reading along here still, you need to
know that one other thing still haunts the operating system schema.
There are still programs which both place the EOF character at the
end of a text file, and also, sadly, those that can't handle it
there when found! If you are modifying any of these or other
control files from text operations in OS/2, you need to be sure
that your editor does *NOT* leave the EOF character at the end of
it. Curiously, even the standard texte editor for OS/2, "E", still
leaves the infernal thing in there!!!

Oh yes, OS/2 has its share of misery, just like every other what
we might call 'near-relgious' experience.. chuckle.

There are millions and millions of these old Classic Pentiums out
there. From my experience, anyone using code on or producing it
for use by others must look at this issue of time slicing and do
what can be done to clean up the code.

Part of the reason I post all this is to let others know that
this issue is very real. It explains why, I suspect, a fair
number of folks have odd instability problems for which they
really do not know the cause .. or at least a probable one.

A mule is kinda like a Packard.

Ask the man who owns one.

Please do not shoot the mule!

Attached is a modification of SNOOZE I wrote a long time ago to
cure some of the problems that Ben Baker's tiny WAIT utility
gave us in the OS/2 DOS-VDM BBS world. WAIT is another horrible
polling CPU trasher that had to be shot .. some way or other.

I've added in Lance's suggestion on using the ENVIRON string to
attempt to detect WIN-NT, to enable time slice releasing, but at
the moment have no time to verify it that game works or not. Too
much else to do right now...

The reason I post this is to demonstrate what *CAN* be done by
thoughtfully applying time slice releasing where practical. At
the same time it illustrates how to break it up in keyboard I/O
sections of a program.

I don't have convenient access to any WIN-NT box to test this at
the moment. So if someone else wants to to it please do and
let me know what happens:

If this is of any value it can go into the source forum, and the
compiled execuatable can go into the other one. I'm interesting
in building bridges, not burning them.....

Err... you can't both claim a copyright and put a work into the public domain.
They're mutually exclusive.

"Oh dear, said the White Rabbit"

Well, we may have not done that quite correctly. Perhaps the
correct way was to release it for any use whatsover. If that's
the position we need to take we should. Lesse - released
for unlimited Public Use.

Want to suggest a better correction phrase that needs to be used?

The intent is to vector the thinking source to the proper places
yet release the use of the code completely.

I think I did this to bring forth another side vector ..

If, if you look closely, the entire example code set forth by
PowerBASIC in its examples carries the notice, and it carries no
notice of right to use whatsoever!

Code block after code block is in there, technically, with no way
for any of your customers, technically, to even incorporate it
into their code! Thus, as an interesting vector to this, is the
idea that absolutely nothing that PB has furnished by way of example
has any right to be used in any code that their users might write.

To my awareness, there is no statement to that right anywhere in
the PowerBASIC documentation or literature, even though we,
the paid-in customers do expect, and suspect do use it and
the licensed property for which we contracted use for.

I'm no guru.

I'm fully aware that what's posted is expected to be used. I'm
also aware that portions of code are also used under similar
chain of authority rights, as was the Microsoft code in it
for the command line I/O sniffing.

Now I want to be honest! I have to give M/S credit! In a way,
chuckle, that was the obligation! So .. any way I go, or
perhaps, almost any way any of us really go, we're trapped
in how we honestly give credit where it's due, even if we
try!

I'll be perfectly happy to release it for unlimited Public
Use, if that will fix it! But in the long run, I have to also
honor where the other part, to which I, as I understand it,
*DO* have the right to incorporate it, came from.

Which I did!

Now do we want to plow dirt and plant some crops that a
lot of us could use and flowers for all to see, or what?

And .. what are we all to do with what you kind folks have
furnished for examples, just between us very pious and holy
folks we all are here?

In your Samples directory, you will find a file called Samples.txt that describes
the usage and distribution rules. If you have questions, feel free to ask.

...

In brief, a copyright is a intellectual property right that gives the owner legal
control over how/whether/when/etc the property may be duplicated. In most countries,
a copyright is automatically granted to any published text, although your legal
recourse is greatly strengthened if you include a copyright notice following certain
specific rules, and if you file a copyright claim with the authorities. So, you
should generally assume that a work is copyrighted unless it contains specific notice
that it is in the "public domain": that is, that no copyright is asserted.

An item in the public domain is not owned by an individual. Anyone can do anything
they like with it.

"Freeware" does not imply "public domain". It is copyrighted software with a broad
distribution license.

I am not a lawyer. These are my personal observations. If intellectual ownership
issues are important to you, check with a lawyer and/or do your own research. A
good source for information is Nolo Press: http://www.nolopress.com/
