No, !PATH is not what you want. You want to be able to
specify a file name inside your program. To do that in
a way that is portable across computer architectures
(you THINK you will be the only one who uses this program,
but you might be surprised at how famous you become
in IDL programming circles!) use the FILEPATH function
to construct the file name.
Check the IDL documentation for CD while you are looking
up FILEPATH, too. If you are interested in locating your
"data" directory with respect to your "programs" directory,
check out ProgramRootDir:
