      SUBROUTINE M_A3SQ

C-    Service routine to M_ANA3, content analysis stage 3:
C-    ready sequence call bank for +CDE +SEQ or +SELF,sname
C-    connecting the called sequences ready for use.
C-    Return IQUEST(1) zero except for +SELF, sname with
C-    sequence sname existing, when the default self material
C-    has to be ignored.
