	SUBROUTINE COMMAND(COMLINE,STATE,KEY,STATUS)
C
C	This subroutine processes a command line by calling
C	the LIB$TPARSE run-time library routines.  It will
C	create a "standard" parameter block for LIB$TPARSE,
C	and then call it.  Any status code returned by
C	LIB$TPARSE will be returned as STATUS.
C
C	This version uses the following LIB$TPARSE options:
C	TPA$M_BLANKS = off, treat blanks as separators
C	TPA$M_ABBRFM = off, abbreviations must be unique
C	TPA$M_ABBREV = on,  abbreviations are allowed
C
C	COMLINE -- Command line to parse
C	STATE   -- State table address
C	KEY     -- Keyword table address
C	STATUS  -- Integer status of command
