XstAbend was added for a reason, I believe Eddie added the function once in the
core routines, but i have no idea for what purpose, but it was for something.
(Something for abnormal terminations or similar).
I don't know if it is called always and exclusively, but if that is the case,
then it should indeed also pass "value".

I don't see a number being passed to XstAbend in your quote, that would
need to be changed somewhere to fix this ...

I'm currently just testing out OpenVPN which allows you to run scripts and
executables.
It depends on the exit code you submit, but there seems to be a large difference
in how OpenVPN interprets the value that XB returns vs the value that a .CMD
batchscript returns while i have learned that exit x should be the same as
QUIT(x) or SET ERRORLEVEL x.
Or the ERRORLEVEL code that is set by XBasic on ending is vanishing along when
the session of the XB application is cleaned up...
If i quickly look in the code, on Windows it just uses ExitProcess from the
win32 API....
When i IMPORT "kernel32" in the PROLOG and then just perform a ExitProcess(1),
the value *is* being interpreted correctly by the host that initiated my
program.

So somewhere in the Quit() token processing, the ExitProcess is always called
with value 0 where it should be called with (userval)

I can see XstAbend using ExitProcess closing with (0) rather than "value"
FUNCTION XstAbend(errorMessage$)
	 MessageBoxA(0, &errorMessage$, &"Fatal Error", $$MB_APPLMODAL | $$MB_ICONSTOP |
$$MB_OK)
	 ExitProcess (0)
END FUNCTION

All other routines call ExitProcess(value), i have tried to follow if "value" is
changed or filled in anywhere
but most of Max's code still grows over my head......

Anyway, for now the workaround is to import "kernel32" and call
ExitProcess(value) directly instead of using QUIT(value)

Hi Group,

I received the message below.  It didn't seem to come through the xbasic YAHOO
group.  I had tried to reply with:  If you are a member of xbasic Grroup you may
download the file from Files>  Members>  XbasicBin . But my email bounced.

Hello Group,

I am a newbie exploring xbasic.  All of my searching on the net
has only led me to xbasic-6.2.3.  Could Someone tell me how to get this version
for linux?

Thanks,

Which path are you trying to create the new file, does XBasic has write access to the path? (Perhaps it was necessary to execute the IDE as #sudo xb instead of xb)
If it returns -1, this is a que to use the systemerror function and read it out what error it stores....

XstGetSystemError (@sysError)
XstSystemErrorToError (sysError, @error)
XstSystemErrorNumberToName (sysError, @sysError$)
XstErrorNameToNumber (error$, @error)
XstErrorNumberToName (error, @error$)

I would not be bothered by submitting data larger than max.
It then depends on how the values above should be interpreted:as no value (IF
value > 500 THEN CurrentProgress = 0) or as max value (IF value > 500 THEN
CurrrentProgress = Max) or perhaps a different case:
IF (Value >= 50) && (Value <= Max) THEN
	 CurrentProgressStatus = Value
END IF

Meaning, you just ignore other values and submit only what matters.
I guess the progress meter will interpret larger values as +Inf and fully scale
out.
If you want to stay on the safe side you just filter all incoming data first and
simply convert any higher values to the max value and send the max value instead
of
just the plain data that you directly get.

Is what is being send increasing at all or are all these figures being randomly
generated? You want to use the progress meter as a sort of gauge meter?

Hi Group,

I took a look at the window code trying to understand what happens when
the data exceeds the maximum value for the XuiProgress.  The reason I
have deduced is related to my S meter data.  The data ranges from 50 to
5000 but I want the display to saturate at 500 and not care about any
data above 500.  Would someone clarify what I should expect from
XuiProgress if it is given data greater than its maximum value?

Here is a small example to transform -200dB (Infinite) to 0 and 0 to 12dB

I'd guess that many people here do ... but you probably don't want to do
that anyway.

Signal strength has always been measured in decibels, which is a
logarithmic scale. What that means is that a difference of 3 dB means one
is twice as loud, 10 dB is 10 times as loud, etc. To change to a linear
scale you'd use exponents, y = 10**(x/10) where x is decibels and y is
your linear value. (Using XBasic notation, "**" means exponent.)

The problem is ... a difference of 20 dB means 100, and 30 dB means 1000.
It's a lot easier to rate things in decibels (or a similar logarithmic
scale), and I'd venture that if you do switch to linear then you'll be
going back to logarithmic in short order.

Hello Group,

First I want to say thank you for the xbasic upgrade it has allowed me
to do some things I was having trouble with.  My most notable upgrade
was the NOHANG option for ttyUSB file I/O.

The data from my radio for the S meter is logarithmic values.  Does any
one know an easy way to convert the logarithmic data to linear values.

If you add debug lines around the S-meter to make them post results in the
console... (Min, max and current for instance)
What are the values that you get vs the values that you get in the compiled
version?
Usually, these ways you get a clue if something functions incorrectly because of
variables that are not what they are outside the PDE or that it must be
something else.
Also post debug lines around your calculator, if min / max and current values
are correctly applied to the progress meter.
And print the kid and gridnumbers in the console so that you know that these
have the correct values outside the PDE as well as within.
What kid-number are you sending it to, what grid number? if you pick those up
dynamically, do they still match outside the PDE?

Hi Group,

Running xbasic-linux-6.3.4 on my 32 bit lap top.  I was able to make
significant progress reading random data through my /dev/ttyUSBn port
(finally).

There is one issue that I would like to see fixed.  In my program I have
a decode function and a display function for displaying the S meter data
in a progress kik of my GUI.  Running this from the xbasic PDE the
progress kid shows changing data.  If I compile my program into an
executable, the program runs as expected except the S meter display is
full scale all the time.

XBasic is 32 bit... Currently 32-compatability modes in the 64-bit Linux
distributions are lousy supported.
To get the 32-bit fontset libraries installed, you need to install Wine to get
that done for instance...
Well, not really, but most 32-bit programs rely on the 32-bit fontset libraries
which are *not* installed with the 32-bit compatability library packs if you
select
those. And there are so a few other things that make the 32-bit compatible layer
crap in the 64-bit Linux distro's.

xbasic-6.3.4-linux-i386-20091110.tat.gz is now in

It includes the option $$NONBLOCK when opening a file

Steven,

If you create new program in the PDE on Linux, import clib, then add
the following line to the Entry() function:

pid = getpid()

The PDE complains that getpid() is undefined, even though it is in defined clib. The very same line of code compiles fine using xb compiler on the command line. Then the problem is that using import clib adds
an unneeded and errant entry in the makefile, which has to then be removed. In the interest of helping the guy out, I created a version
that I knew would compile and run given the instructions I provided.

I'm not sure why he thinks you couldn't use it in the PDE, you'd just have
to import your clib (instead of the individual "open", "read" and "close"
commands). That's why it works when compiled - even if you didn't have an
IMPORT statement for your clib, XB has one in its own libraries.

Hi Group,

I have been told about using the C open() in Xbasic to get a NO_HANG
open.  This leaves me cold.  My primary concern is my program is still
under developement and having to recompile each time I make a change
seem counter productive.

Hi group,

I think my copy of xbasic-6.3.3-linux-386 may  have gotten corrupt.
Where do I find a fresh copy.
