Very much kludgey. I had hoped that someone with a smarter answer would
have responded by now...

Could you wrap your IDL call in a shell script where you also set your
own environmental variable and use that instead? For example,

$ export CWD=$PWD && idl
IDL> cwd = getenv('CWD')

I tried that already - it gives the same answer.

The directory is correct when I'm in "interactive" idl, but NOT for
runtime.

Someone else would have to answer the "is this a feature" question. An
ugly work-around would be to pull the environmental variable
corresponding to the system's current working directory and start from
there. I only say it's ugly because you have to directly rely on an
environmental variable and just never like having to write code that
might not transfer cleanly if you change the machine that it's running on.

I can get the current working directory on my system with:
cwd = getenv('PWD')

Don't know if that helps or not.

It's not necessary to make an additional export

pro testme
print,getenv('PWD')
end

IDL> compile,'testme'
IDL> exit
> cd Documents
> idl -rt='../testme.sav'
% Restored file: IDLRTMAIN.
/home/me/Documents

compile is from our library. We have included a history function to show
what's all is in the sav file.
