! FUNCTIONAL DESCRIPTION:
!
!	This routine writes out the portion of a message giving a count.
!	The count can be 48 bits long or less
!
! FORMAL PARAMETERS:
!
!  N 			the count pointer, which is written as a decimal number unless it
!			is zero, in which case it is written as 'No'
!
!  S 			a pointer to a string of characters which is written after the count,
!			followed by an 's' unless the count is exactly 1.
!
!  L 			the length of the sting pointed to by S.
