C
C  PURPOSE: TO EXTRACT AND  INTERPOLATE  ZERO-DENSITY  IONIZATION  RATE-
C           COEFFICIENTS FOR GIVEN ELEMENT NUCLEAR CHARGE AND DATA-BLOCK
C           FOR AN INPUT SET OF ELECTRON TEMPERATURES.
C           
C           USES THE SAME ROUTINES USED BY ADAS502, EXCEPT FOR:
C
C           'E2FILE' - WHICH OPENS THE REQUESTED FILE.
C           'E2CHKB' - WHICH CHECKS INPUT  VALUES  ARE  CONSISTENT  WITH
C                      THE SELECTED DATA-BLOCK 'IBSEL' AND   'IBSEL'  IS
C                      IN RANGE.
C
C            THE FIRST OF THESE FUNCTIONS IS CARRIED  OUT  IN  'ADAS502'
C            VIA ISPF PANELS USING THE ROUTINE 'E2SPF0'  -  ADAS502 DOES
C            NOT REQUIRE THE ROUTINE 'E2CHKB' AS THE USER CANNOT  SELECT
C            AN INVALID VALUE FOR 'IBSEL' OR 'IBSEL'/ELEMENT COMBINATION
