This problem also exists in the MS-DOS world. How should a program
determine where to look to find other parts of itself (overlays,
resource files, etc.).

One solution is to have the program use the PATH environment variable,
and look in all those places. Can anyone tell me if TOS has environment
variables? Are they set when using GEM, or only when using a shell?

Another solution is to load a resident program which intercepts all
opens and does its own searching. This is available for MS-DOS, but
I don't know the details of its inner works.

If neither of these is available, TOS programs may just have to look
in a few predetermined places (/, /bin, /auto, etc.). I hope something
else can be done.
