+c STRPAK -- Pack an SPP character string into a C string, i.e., a sequence
+c of characters stored one per byte, delimited by EOS='\0'.  The operation
+c may be performed in place.  This version assumes that the host character
+c set is ASCII and hence no lookup table reference to map character sets is
+c needed.  If this is not the case, code must be added to convert to the host
+c character set.
+c
+c N.B.: If sizeof(XCHAR)=1, XEOS=EOS, and the host character set is ASCII,
+c and the operation is being performed in place, then this procedure should
+c do nothing.
+c 
+c N.B.: This code ASSUMES that XCHAR is implemented as INTEGER*2 and that
+c both XEOS and EOS are 0.
+
+	subroutine strpak (instr, outstr, maxch)

+	character*1 outstr(*)
+	integer maxch
