 RIGAL for UNIX. Source code in C. Includes RIGAL to C compiler, examples,
 detailed language description and user guide.

 The BUGs fixed (in 445, after 444)
  -  capitalisation  of characters in the scaner.
  -  more options added to #CALL_PAS(80). See 80.txt for description.

 445.1  - Fixed bug in scaner, the problem was with the last line
          if it has no end-of-line character
  
 445.2  - Fixed bug in PRINT statement. When compiled it worked
          differently with and without -p flag
        - $rig/rc <program> -c  -P -DXX
          gives the trace for compiled task, similar to
          interpreter produces.

 446   - Fixed bug in the A[i]!!:=X and A[i]++:=X statements.
         (Earlier they had no effect if A[i]==NULL and X is
          a variable).
       - option  "P" added to   #CALL_PAS(80). See 80.txt.

 446a  - Fixed a very rare bug with ley_.c , Rigal scaner.
         It had strange code fragment for reading strings,
         I removed it.
         Fixed the case when "!." did not work after "COPY".
         Applies to c2.c, erm.c,  functions "copyop()".
