Updated:
         2002-March   V.McLane: Provided source code on VMS (DEC-Fortran)
         2002-May     V.Zerkin: Ported from VMS to Windows, Linux:
                      - Dictionaries were re-organized to direct-access files;
                      - New program DANLO written to create new Dictionaries
                        from dictionaries-backup file (DAN_BACK_NEW.XXXX)
                      - Subroutines to access new Dictionaries
         2004-May     V.Zerkin: recompiled on Linux with Fortran:
                      - Lahey/Fujitsu Fortran 95 Compiler Release L6.20b
         2005-April   V.Zerkin
                      - Windows/Linux: EXFOR Dictionary 9086
                      - debugging: usage of Status-field in Dictionaries

                      - EXFOR Dictionaries were re-organized (9188):
                        7-->7+207, 13-->213, 27-->227+209, 36-->236
                      - debugging: correct checking N1, N2 in ENDENTRY, DATA
         2005-Dec.    V.Zerkin
                      - debugging: correct work in TRANS mode

                      - Windows/Linux: EXFOR Dictionary 9090
         2006-Dec-12  V.Zerkin
                      - Windows/Linux: EXFOR Dictionary 9093
                      - finds missing '(' in REACTION keyword
                      - allows isomer extensions "-L","-L1","-L2"
                        in REACTION and DECAY codes
                      - Wildcards for SF7 during cheching of SF5-8:
                        done using Dictionary-33 (works, but still under testing)
                      - indication of SAN in the right column of error-message
                      - input file name is indicated in the error file and 
                        on the user's terminal
                      - length of input file name is expanded from 50 to 65
         2007-Jun-08  V.Zerkin
                      - Windows/Linux: EXFOR Dictionary 9094
                      - Wildcards for SF7 during cheching of SF5-8:
                        improved algorithm - now uses all Dictionary-33 and 227;
			(full test and Dict-236 having only wildcards were
			 prepared by O.Schwerer)
                      - debugging (according to S.Maev, 2007-06-06 e-mail)
                      - adopted to Mac OS X (using g77 fortran compiler)
         2007-Oct-02  V.Zerkin
                      - Windows/Linux/Mac: EXFOR Dictionary 9095 (wildcards only)
                      - debugging: correct processing of N1,N2 in DATA and COMMON
         2009-Oct-07  V.McLane
                      - recognize NPART in SF4
                      - check that author's name is longer than one character
			(to find commas after initials)
		      - allow alphabetic characters in reference page number
		      - check coding for new ERR-ANALYS format (not completed)
         2010-Mar-30  V.Zerkin
                      - debugging: completed checking new ERR-ANALYS format
                      - introduced definition of input file name in command line
		      - standard procedure to run from Windows-desktop
                      - Windows/Linux/Mac: EXFOR Dictionary 9100
         2011-Jan-07  V.Zerkin
