I guess it has to be
A_IncludeDir="%IncludeDir%"


But I'm not so sure if it is even possible to set a variable through Run.

It should work, but the variable is only valid for that DOS session, as it is when you do it manually. So this will work:
If you want it make for every DOS session, I think you can only make it permanent in e.g. Autoexec.bat. But that's no solution for you if I understand your goal.

Do you mean doing a permanent change of the environment?
In this case, set doesn't do it: open a cmd box, set a variable, close the cmd, open a new one: the value isn't there.
You have the EnvSet command, but it has the same problem: only subtasks (like those ran with Run or RunWait) will see it.
The problem can be solved, but it depends on your system.

On old Dos-based systems (Win9x), you have to alter autoexec.bat and reboot... Actually, Microsoft provided an exe (WinSet?) doing a permanent change to the current system, probably using some voodoo.

On NT-based system (Win2k, WinXP), I believe these values are saved in the registry. I changed user and system environment with the System Properties dialog, monitoring with Regmon. Found:
HKCU\Environment\MyUserEnvironmentVariable
HKLM\System\CurrentControlSet\Control\Session Manager\Environment\MySystemEnvironmentVariable
Use with care...

oh yes, that works very well, thank you.

That's logical: they have a very different way to storing/managing the environment variables, and if, like I think, WinSet use some voodoo to do its trick (like manipulating directly the memory of Windows...), it has to crash on WinNT...

Last notes: in WinNT, I had to logout and relogin to have the values taken in account. It seems no longer needed in XP. The running consoles will not take in account the change. Perhaps a broadcast of the change should be done to be consistent, if changing a value that may affect a running application.

Actully, no. A_IncludeDir is a new variable that will be accessible in ahk: %A_IncludeDir%. This will allow dynamic inclusion of files when and if #include is ever improved to handle user or env variable.

Functions from my download here: http://www.autohotkey.com/forum/viewtopic.php?t=5016 could be included like this someday:

Correction, it is possible to make the variable permanent, with Setx tool from resource kit Win2000! But it's the opposite of the normal behaviour namely, the environment variable is valid for all next DOS sessions, and not the current one.
More information here. And by searching the forum on Setx, I found Bobo's post.
