I think that files should be searched for as follows.

if environment variable set then
 use it
 if file found goto success

if path in argv[0] then
  use it
  if file found goto success

use current directory
if file found goto success

use hardwired path
if file found goto success

:failed
exit gracefully or use reasonable defaults

:success
do whatever you want


Please note that the goto need not be taken literally (please).

I think one should be able to expect users to have a late version of MSDOS.
If we don't we are not going to get anywhere. It will become difficult to
phase out bad habits (e.g. writing directly to the screen) and use new tricks.
I feel sorry for people that cannot upgrade, but everybody can't stand still
just for those few. In other words; if msdos v5 proves to be good, then I
expect that I will have to upgrade to that version in order to use new
software. I think that is reasonable.
