C ****************** FORTRAN77 SUBROUTINE: E2FILE *********************
C
C PURPOSE: TO OPEN AN IONIZATION RATE-COEFFT 'IONELEC' DATA SET
C BY DEFAULT, OR AN ALTERNATIVE DATA SET IF REQUIRED, FOR
C IONIZING ION WITH NUCLEAR CHARGE 'IZ0'
C THIS WILL BE CONNECTED TO UNIT 'IUNIT'.
C
C DATA SET OPENED: $ADASUSER/<DEFADF>/<GROUP>(OPTIONAL)/<TYPE>/
C <GROUP_EXT>#<ELEMENT SYMBOL>'
C
C CALLING PROGRAM: SSZD
C
C SUBROUTINE:
C
C INPUT : (I*4) IUNIT = UNIT TO WHICH DATA SET WILL BE CONNECTED
C INPUT : (I*4) IZ0 = NUCLEAR CHARGE OF EMITTING ION REQUESTED
C
C OUTPUT: (I*4) IRCODE = RETURN CODE FROM SUBROUTINE:
C 0 => DATA SET SUCCESSFULLY CONNECTED
C 1 => REQUESTED DATA SET MEMBER DOES NOT
C EXISTS - DATA SET NOT CONNECTED.
C 9 => REQUESTED DATA SET EXISTS BUT CANNOT
C BE OPENED.
C OUTPUT: (C*80) DSNAME = NAME OF OPENED DATA SET UNDER UNIX
C
C (I*4) IDLEN = LENGTH, IN BYTES, OF FIXED 'DSNAME' PREFIX
C (I*4) LENF1 = FIRST NON-BLANK CHR OF 'DSNAME' GROUP PART
C (I*4) LENF2 = LAST NON-BLANK CHR OF 'DSNAME' GROUP PART
C (I*4) LENF3 = FIRST NON-BLANK CHR OF 'DSNAME' TYPE PART
C (I*4) LENF4 = LAST NON-BLANK CHR OF 'DSNAME' TYPE PART
C (I*4) LENF5 = LAST NON-BLANK CHR OF 'DSNAME' USERID PART
C (I*4) LENF6 = LAST NON-BLANK CHR OF 'DSNAME' USERID PART
C (I*4) LENF7 = LAST NON-BLANK CHR OF 'DSNAME' EXTENSION PART
C (I*4) LENF8 = LAST NON-BLANK CHR OF 'DSNAME' EXTENSION PART
CA (C*1) HASH = '#' IF NON-BLANK EXT, ELSE ' '.
C (C*2) XFESYM = FUNCTION - (SEE ROUTINES SECTION BELOW)
C (C*2) ESYM = ELEMENT SYMBOL FOR NUCLEAR CHARGE 'IZ0'
C (C*3) USREXT = ADAS SOURCE DATA FILE EXTENSION
CA (C*80) USERID = ADAS SOURCE DATA USER ID
C (C*8) USRGRP = ADAS SOURCE DATA GROUPNAME
CA (C*80) USRTYP = ADAS SOURCE DATA TYPENAME
C (C*5) DEFADF = DEFAULT DATA DIRECTORY, I.E. ADF13
C
C (L*4) LEXIST = .TRUE. => REQUESTED DATA SET EXISTS.
C .FALSE. => REQUESTED DATA SET DOES NOT
C EXIST.

C K1/1/57
C JET EXT. 4941
C DATE: 11/10/91
C
C UPDATE: 10/03/93 - PE BRIDEN: ADDED CALL TO XXUID AND USERID VARIABLE
C - NOW ALLOWS ANY INPUT DATASET USER ID.
C UPDATE: 2/09/93 - HPS : ADDED CALL TO XXSSZD AND USRGRP, USRTYP
C AND USREXT NAMES
C - NOW ALLOWS ANY INPUT DATASET FILENAME
C AND EXTENSION
C UPDATE: 23/11/93 - PEB : CORRECT ERROR - A '.' HAD MISTAKENLY
C BEEN PLACED BEFORE THE MEMBER NAME IN
C VARIABLE DSNAME.
C
C UPDATE: 10/11/94 - L. JALOTA: MODIFIED CODE FOR RUNNING UNDER UNIX
C USING NEW FILE NAMING CONVENTION.
C "ACTION" KEYWORD IN OPEN COMMAND IS IBM
C SO REMOVED HERE.
C ADDED DEFADF
C UPDATE: 22/11/94 - L. JALOTA: TIDIED UP CHARACTER LENGTH DEFINITIONS
C
C UPDATE: 24/03/95 - HPS : INTRODUCED HASH TO ELIMINATE # IN FILE IF
C THERE IS NO EXTENSION PART OF THE FILE NAME
C ALTER LOGIC TO ALLOW USRTYP, USREXT TO BE A
C SINGLE CHARACTER.
