! ABSTRACT: Portal to the routines which generate default
! move-matching and move-others-matching transforms.
!
! AUTHOR: Sandy Clemens, Creation Date: 25-Oct-84
!
! EDIT HISTORY:
!
! 3 Clean up copyright notices. Change LIBRARY 'DIUMSG' to
! 'DIU'. Clean up condition handling. Remove some of the
! debugging calls to DIU$DUMP_TRANSFORM. Fix dot bug in
! DIU$DEF_TRANS.
! Sandy Clemens 14-Jun-85
!
! 10 Make default transform generation code use the DIU top level
! condition handler rather than DIU$TRANS_HANDLER.
! Sandy Clemens 20-Jun-85
!
! 236 Change library of DIXLIB to DIUDIX.
! Sandy Clemens 19-Jun-86
!
! 253 Change libraries to new names.

!
! This routine is the portal to the routines which generate
! default move-matching and move-others-matching transforms.
! This routine can be called with subtrees and/or to perform
! a move-matching on a structure, etc.
!
! FORMAL PARAMETERS
!
! mm_flg is a flag which indicates either move_matching
! or move_others_matching
!
! src_tree is the address of the record description
! tree or subtree for the source record
!
! dst_tree is the address of the record description
! tree or subtree for the destination record
!
! trans location where the address of the first transform
! nodes should be returned
!
! dimsrc is the address of the current DIMS node which
! applies to the source record description subtree
! or 0 if none
!
! dimdst is the address of the current DIMS node which
! applies to the destination record description
! subtree or 0 if none
!
!
! IMPLICIT PARAMETERS
!
! None
!
! ROUTINE VALUE
!
! STATUS; ALSO modifys address passed in parameter TRANS
