OK MS-DOS hackers - here's a tough one.  Can anyone tell me what the purpose of
the different fields in the ms-dos command table are:

It consists of:  1 byte - number char in command name + 1
                 x byte - the command name
                 1 byte - 00 or 01, purpose unknown
                 2 byte - an address/offset of some sort

What I am interested in is how to locate the code that is associated with a
given command. The short term goal here is to reverse the operation of the
/w flag on dir, which causes a 'wide' list across the screen instead of the 
usual list down the screen. Thanks for the help.
