  FileInput_get_flags doesn't appear to work for locating

 the end of a file. Use Input_get_flags instead.



   Bad Code

   --------



 value = FileInput_get_flags(&input_file) & FLAG_EOF;



   Good Code

   ---------



 value = Input_get_flags(&input_file) & FLAG_EOF;

 i = -i;

Cybiko C Compiler v1.0.18 Array Bug

-----------------------------------



  When using arrays, trying to do math in the first parameter

will produce bad code but there is no compiler warning.



   Bad Code

   --------



 int x,y,i;

 i = Test[y/4][x/4];



   Good Code

   ---------



 int x,y,i,ox,oy;

 ox = x/4;

 oy = y/4;

 i = Test[oy][ox];



   Good Code

   ---------



 int x,y,i,oy;

 oy = y/4;

 i = Test[oy][x/4];







Cybiko C Compiler v1.0.18 draw_lib Bug

--------------------------------------



 This is the function to use to draw "sprites" to the screen.



 If you wish to use the 'BM_FLIP_X' and 'BM_FLIP_Y' attributes

(for horizontal &/or vertical flip of your graphic) then make sure

that these graphics are in their own file (in the filer.list file).

and that no other extremely large graphic is in the same file.

A large graphic in the same file will cause the FLIPs to not work.

The result will be nothing drawn.
