!++
! FUNCTIONAL DESCRIPTION:
!
!	This module produces a formatted text string of the contents
!       of an 8 bit message buffer. Eight 8 bit bytes are produced
!       per text line. The byte offset into the buffer is printed
!       as six octal characters at the start of each line. The contents
!       of the buffer are then printed as both octal triplets and
!       converted to ASCII text. Unprintable characters are printed as
!       spaces in the text portion. The text portion of the line is
!       enclosed in asterisks (*).
!
! FORMAL PARAMETERS:
!
!	BIAS ->	A BLISS value which represents a byte offset into the 
!		beginning of the buffer to be displayed.
!
!	PTR ->	A character string pointer to the buffer to be displayed
!
!	LNG ->	A BLISS value which represents the number of bytes
!		to be displayed.
