Automatic Filename Extensions

in UNIX that's fine, a name like a.b may have .EXT added, but it won't
work on other systems, such as MSDOS and VMS. How about isolating just
the filename via strrchr (or rindex) and then using strchr as you have
been. Something like:
[...]
/* End of text from convex:comp.lang.c */

Actually MSDOS is a little more perverted than you have illustrated,
i.e. the name:
     d:\bin\glarp.20
may be a filename _or_ a directory.  The only way to tell for sure is
to use something along the lines of an access() call to check it.
I've found no syntax yet that will guarantee what that name means.
