     RATFOR is a structured Fortran  preprocessor  providing
"IF" - "ELSE", "WHILE", "FOR", "DO", "REPEAT" - "UNTIL", and
"BREAK" and "NEXT" constructs.  Also supported  are  INCLUDE
files,  DEFINE  for  symbolic  constants,  use of >, <, etc.
instead of .GT., .LT., etc, and the "RETURN VALUE" construct
in functions.

     This version of  RATFOR  is  originally  from  Lawrence
Berkely Labs;  the major enhancements in it are:

      1. Ability to specify  a  format  statement  in  READ,
         WRITE, ENCODE, and DECODE statements;

      2. True  line   continuation   using   the   underline
         character;

      3. Production of properly indented upper case  Fortran
         code with comments passed through;

      4. Addition of a /SYMBOLS switch to the  command  line
         to specify reading of the SYMBOLS file;

      5. Ability to deal with single quotes on a line.


     This version of RATFOR should be used if  you  want  to
compile  the RATFOR source to the MTREK multi-user star-trek
also provided on this tape.
