OK.  So, put a wrapper around DCL.EXE and introduce your OWN ^R handler 
to read in the recall buffer and provide editing.  Of course, a ^R has
been used as a screen refresh in a number of VMS products/utilities, so
you willl probably want to use some other control char.  You can still
specify your OWN CLI in your UAF record!
