August 14, 1996; Richard L. Goerwitz
Requires: UNIX or MS-DOS
This file is in the public domain.
Suspends, in turn, the paths supplied as args to getpaths(),
then all paths in the PATH environment variable. A typical
invocation might look like:
open(getpaths("/usr/local/lib/icon/procs") || filename)
Note that getpaths() will be resumed in the above context until
open succeeds in finding an existing, readable file. Getpaths()
can take any number of arguments.
