C     | SUBROUTINE CPL_IMPORT_EXTERNAL_DATA
C     | o Routine for controlling import of coupling data from

C     *==========================================================*
C     | This version talks to the MIT Coupler. It uses the MIT
C     | Coupler "checkpoint1" library calls.

C     Fetch data from coupling layer. Note MIT Coupler checkpoint1
C     does not allow asynchronous extraction of data, so ordering
C     has to be consistent with ordering coupling layer.
