Why don't you create your own variable. Here is an IDL
program that is handy:

PRO PWD
CD, CURRENT=thisDir
Print, thisDir
END

Used like this to tell you what directory is the current
directory:

IDL> pwd
G:\IDL\Coyote

You could probably turn this into a function easy enough. :-)

If you want to write programs that can find data files
and other files based on the location of the IDL source
code, use PROGRAMROOTDIR:

http://www.dfanning.com/programs/programrootdir.pro

Use it like this inside of a program named DOIT, to locate
a data file in the same directory as doit.pro:

datafile = Filepath(ROOTDIR=ProgramRootDir(), 'doit_data.dat')

Cheers,

David
