          Abstract:  Reese Basic is a highly upgraded version of  what
          used to be a DECUS library program for DOS.
 
          1.  Full FILES-11 I/O is supported, (fixed length random ac-
              cess, shared mode, etc.)
 
          2.  String functions and user  defined  functions  are  much
              more  flexible than in either the original version or in
              DEC's BASIC-11.
 
          3.  Multi-user implementation  is  supported  with  separate
              pure and impure areas.  (IAS and RSX-11D only.)
 
          4.  Since it is an interpreter, it includes the special  de-
              bugging commands:  STEP, CON and SET TRACE.
 
          5.  Although an interpreter, significant manipulation of the
              source program is done to speed up operation.
 
          6.  OVERLAY and a data preserving CHAIN are also supported.
 
          7.  A clean  "break"  feature  is  implemented  via  the  TT
              handler.
 
          8.  a number of BASIC+2-like features have  been  added  in-
              cluding:   virtual  arrays,  integer and byte variables,
              continued lines and IF-THEN-ELSE.
 
          9.  User written machine language subroutines are supported.
 
          10. The capability of SPAWNING another task is supported.
 
          Also included on the tape are  two  entertainment  programs,
          MURPHY,  which  randomly  produces versions of Murphy's law,
          and MAY, which gives curses of the form  "May  the  bird  of
          happiness ..."
