Mike Belshe notes:
------------------
I see two meanings for the FILE command: 1)  Used to convert between
different file types.  This has no meaning in the POSIX context because the
POSIX context really only understands one filetype - "bytestream".  2)  Used
to associate one filesystem name to another filesystem name.  This can be
done with the link (ln) command.
 
Dan Hollis Notes:
----------------
MPE: FILE DUMMY=DUMMY2          POSIX:  ln -s DUMMY2 DUMMY
(note: this will place an actual file on the drive, e.g. a permanent file
equation so to speak. This is Posix symbolic linking of files.)
 
There is no reason you have to execute these commands from the posix shell.
E.g., LS.HPBIN.SYS "-al"  works just fine from the CI;  same as:  "ls -al"
does from the Posix shell.
