You can also use environment variables instead of hard coding file paths.
If you have something like:
SELECT DataFile ASSIGN TO "DataFile" ...
in a program, you can set the environment variable DD_DataFile to the full
path to the file. That can make it a little easier to switch between test
and production files. I wonder if that variable name syntax was inspired by
MVS JCL DD statements.
