/COMMAND[=filespec] (default)
/NOCOMMAND
Controls whether to execute your default login command procedure
when you log in. Use the /COMMAND qualifier to specify the
name of an alternate login command procedure. If you specify a
file name without a file type, the default file type .COM is
used. If you specify the /COMMAND qualifier and omit the file
specification, your default login command procedure is executed.
Use the /NOCOMMAND qualifier if you do not want your default
login command procedure to be executed.
