One caution with this program...  This only gives the command tail of
the current process (the program accessing the command line that
invoked it).

The original poster was intending to write a TSR that stored command
lines (possibly to be able to recall them later -- much like CED).  I
would suggest getting the book "Undocumented DOS" -- there is a chapter
on command processors which might be of use.  I haven't gotten around to
reading that particular chapter yet, so I can't be sure if it gives the
info the original poster wants, but it should be a start.  For those
who are interested in writing TSR's, it's a must-have !
