Mixed case filesnames could be a real headache on a Apollo system running
Domain/IX (Apollo's flavor of Unix). On the one hand, Unix is case sensitive;
on the other hand, Aegis (the underlying "native" OS) is case-insensitive.
How does Apollo deal with this? A Unix name like "FooBar" becomes an
Aegis name like ":foo:bar".
Ideally, this doesn't make a bit of a difference, but in practice, Domain/IX
sometimes :) does break and you have to drop into Aegis to fix things, and
Aegis commands have an odd habit of sometimes not being able to deal with
filenames containing ':'s.
By the way, similar considerations apply to Eunice running under VAX/VMS.
Uppercase characters in Eunice filenames get '$' prefixed (or is it suffixed?)
when seen from VMS, and VMS has a 14 char filename, 14 char filetype limit.
So, you're really talking about limiting filenames to 7 chars plus a '.'
plus N chars for the "filetype". Why would anyone try to port X to Eunice if
X ports to VMS? Who knows, but it's still a potential problem.
