!
!   ABSTRACT: DIUMLB is the library of definitions and data structures
!             used by the Mapping routines (see module DIUMAP).
!
!   AUTHOR: Sandy Clemens, Creation Date: 25-Oct-84
!
!   EDIT HISTORY:
!
!       3	Clean up copyright notices.  Change 6-char macros
!               to reflect changes in other modules.
!		Sandy Clemens	14-Jun-85
!
!       10	Make default transform generation code use the DIU top level
!               condition handler rather than DIU$TRANS_HANDLER.
!               Sandy Clemens	20-Jun-85
!
!       14      Add transform execution code and conversion warnings report
!               code.  FILES:  DIUETR.BLI (NEW), DIUCSR.BLI (NEW), DIUDMP.BLI,
!               DIUABO.B36, INTFAC.BLI, DIUTLB.BLI.
!               Sandy Clemens	15-Jul-85
!
!       23	Remove DIU$CDD_EXTRACT from DIUTUT module and put it
!               into INTFAC.  It's only part of INTFAC, not DIU.  It was
!               commented out of DIUTLB anyway...  FILES: INTFAC.BLI,
!               DIUTUT.BLI, DIUTLB.BLI.
!               Sandy Clemens	18-Jul-85
!
!	25	Allow initial values of dimensionned fields.
!		Charlotte Richardson	13-Aug-85
!
!  236  Change library of DIXLIB to DIUDIX.
