C  ****************** FORTRAN77 SUBROUTINE: CDSUM *********************
C
C      	PURPOSE:  TO  FETCH  A SUMMARY OF THE DATA CONTAINED IN THE
C		  BUNDLE-NL POPULATION STRUCTURE FILES OF TYPE ADF26.
C
C      	CALLING ROUTINE : ADAS313
C	
C	INPUT	:
C
C		(CHR)	INFILE		: FILENAME FOR WHICH DATA HAS
C					  TO BE EXTRACTED FROM.
C		(I*4)	INUNIT		: FILENAME STREAM.
C		(I*4)	MAXNE		: MAXIUM NUMBER OF DENSITIES
C		(I*4)	MAXEB		: MAXIMUM NUMBER OF BEAM
C					  ENERGIES.

C		(R*8)	TEREF		: REFERENCE TEMPERATURE ( eV ).
C		(R*8)	NEREF		: REFERENCE DENSITY ( cm-3).
C		(R*8)   EBREF		: REFERNCE ENERGY ( eV amu-1 ).
C		(I*4)	INA()		: REFERENCE ARRAY FOR DENSITY.
C		(I*4)	IEA()		: REFERENCE ARRAY FOR ENERGY.
C		(I*4)	ITA()		: REFERENCE ARRAY FOR TEMPERATURE.
C		(I*4)	INREF		: ARRAY INDEX OF REFERENCE DENSITY.
C		(I*4)	ITREF		: ARRAY INDEX OF REFERENCE TEMP.
C		(I*4)	IEREF		: ARRAY INDEX OF REFERENCE ENERGY.
C		(I*4)	INCOUNT		: NUMBER OF TARGET DENSITIES.
C		(I*4)	IECOUNT		: NUMBER OF BEAM ENERGIES.

C		  - With certain compilers array dimension variables 
C			must be declared before they are used. Move the
C			integer declerations before the array definitions.
