History of changes for
             Extended Batch Language Version 3

1.  Version 3.01a

    Initial release.

2.  Version 3.01b

    Fixed bug that  caused some text in the prompts for READ
    or INKEY commands to print smiley face characters.

3.  Version 3.02a

    *   Fixed  bug if a "call"  to a  second batch file  was
        made   using   the  command  "BAT   SHELL   BAT   /R
        Second.BAT"  and external functions were  ALSO used.
        The bug caused a system hang.

    *   Changed the  algorithm that looked  up  the keywords
        to improve execution speed.

    *   Fixed  bug  so that  pressing  break  will  properly
        reset   the  CALL-RETURN  pointer  for   batch  file
        subroutines when terminated.

    *   Protected the functions 72,7A,7B,7C,7D so that  they
        cannot be used by user  extensions  if the transient
        EBL is not  in memory.  All will return AX=-1 if EBL
        is not  in  memory. If  OK,  it  will always  return
        AH=0.

    *   The   IF,THEN,ELSE  commands  can  have  CALL-RETURN
        commands between them and the status  of  the  IF be
        saved and restored properly.

    *   If a  CLS command is followed immediately by a  READ
        command with a prompt, the cursor  position will now
        be correct.

    *   Changed  spacing  of  parameter  line  within  SHELL
        command  to exactly match  what  DOS  creates.  Some
        programs   may  be  sensitive  to  this  and  failed
        previously.


4.  Version 3.03a

    *   Fixed  all READ and PARSE commands  so that contents
        read will not  be altered  by any external  function
        packages that are loaded.

    *   External function names must  now be  from  3  to 15
        letters long. EBL  will not call  external functions
        with  names   too  short  or  long.  Exceptions  are
        functions (like  the extended variables)  with names
        starting with "&" (ampersand).

    *   The PARSE command will  now allow an  empty token to

        be  parsed.  No  error  will  be  reported  and  the
        resulting variables will be made empty.

    *   Quoted  string  mode  will  be effectively  disabled
        (/Q-  option) during any READ or PARSE command. This
        will allow entry of  strings  contain  quotes,  even
        partial ones.

    *   Further  optimized  command  recognition to make EBL
        even faster.
