I am building my own UNIX work a like environment for DOS, and one of
the things that I would like is the ability to do command line 
completion via the TAB key.  I know 4DOS does this, but using 4DOS is
out of the question since it won't work with my configuration.

Anyway, the two approaches I see are :

when the tab key is pressed then scan the current directory for a closest
match.

OR...

when the TSR is loaded, scan the current directory and save to a buffer.
When CD is issued or when a file is deleted, renamed, etc. update the
buffer.  Check buffer when tab key is pressed.

Which is recommended?

Also, I wouldn't want to execute the TSR if I was, oh, in WordPerfect.  How
do programs like DOSEDIT know if they are in another program?  It seens
that DOSEDIT traps int 21 and catches all EXECs...is this correct?

Finally, I have DOSEDIT and don't know anything about it!  Is there way
to get help on it, and how do I set up the size of the history buffer
and set up aliases?

Thanks,

Brian
