+*DECK SPHSCO
+      SUBROUTINE SPHSCO(IPCPO,ICAL,IMPX,IMC,NMIL,NGRP,SPH)
+*
+*-----------------------------------------------------------------------
+*
+*Purpose:
+* Apply a new set of SPH factors for an elementary calculation in a
+* Multicompo.

+*Author(s): A. Hebert
+*
+*Parameters: input
+* IPCPO   pointer to the Multicompo (L_MULTICOMPO signature).
+* ICAL    index of the elementary calculation being considered.
+* IMPX    print parameter (equal to zero for no print).
+* IMC     type of macro-calculation (=1 diffusion or SPN; 
+*         =2 other options).
+* NMIL    number of mixtures in the elementary calculation.
+* NGRP    number of energy groups in the elementary calculation.
+* SPH     SPH-factor set to be applied to the Multicompo.
