Looks the registry manipulation in below mentioned manner creates REG_SZ
registry entry. Is there a way to create registry entry type that is say
REG_DWORD or REG_EXPAND_SZ? I would be more interested in the process that
creates REG_EXPAND_SZ entry.

It also appears that '...' represents special semantics at the file system
level in UWIN, true? 

I tried 'cd /reg/HKLM/SOFTWARE/AT&T Labs/UWIN/5.0/Install/' and then
executing 'ls -al ...', 'ls -al .' or 'ls -al' did not display any contents.
However, executing 'ls -al .../Home' gave me correct directory entry. I then
tried to explore further and did 'cat ...' but it did not display all
sub-keys in that hive. Executing 'cat .../Home', nonetheless, displayed
value of that key. That leads me to believe that file system semantics
cannot perform searches but you can display key value if you precisely know
the entire path to the key.



this sequence shows how you can use the ... special directory to write, read
and delete name=value registry subkeys
