System variables

Hi all!

Sorry if I´m asking a stupid question here...

Where are all system variables saved? In help it says "Registry", but if you
search for "Textfill" for example you can´t find anything.

I want to access them from a external program.

Do someone know where I can read about them or where I can find some tip
about generell programming?

Thanks in advance!

At Command: prompt,
Type in:
setvar
?

Hi Bob!

Thanks, but I was wondering if the variables are saved somewhere so that you
can access from a external program somehow...

As it says "Registry" in the help files i was wondering what registry they
mean.

Profiles etc. have their own registry key, but some of the system variables
such as textfill etc. are saved somewhere else?

I have found that some of the variables are saved in the profile and some
are not.

Right or wrong?

Yes,
'Some' of the variables are stored in registry, not all ..
In Visual Lisp, there are ways to 'read' or 'write' values
to the registry. Pretty tricky stuff. If you are not 'totally' comfortable with modifying the registry, I would suggest just
setting the variables you need to adjust with straight - good old AutoLisp.

Thanks Bob.

What I want to do is to read and write system variables from a external
program.

Do you think its possible to do that?

Thats also why i´m not satisfied with just setting the variables from
AutoCAD, maybe I´m trying to solve this in the wrong way?

/Fredrik

with modifying the registry, I would suggest just

 

AFAIK, it can't be done. But if you tell us what you're trying to
accomplish, someone may have a scheme that will work for you. Since system
variables are only in effect when AutoCAD is open and functioning, there
would seem to be little or no advantage to setting them externally. BTW, if
you look in HELP, you'll see where each is stored: some in the drawing file,
some in the registry, and some not at all.

Bit of a 'cludge', but you (could) have the external program
(read / write) the acaddoc.lsp (text based). Output / append
to this file - something like..
$O = "(setvar " & chr(34) & "OSMODE" & chr(34) & " 0)"
Print #1, $O
...
Next time Acad is started, will read these settings..
