                            *** MICRO-C Features ***
   
   
   
       -   Very easy to port, not tied to any processor architecture.
   
       -   Lots of documentation (>200 pages) and example programs.
           Includes detailed information on porting the compiler.
   
       -   Includes built-in and external pre-processors.
   
       -   Includes post-processor optimizer for even better performance.
   
       -   Over 130 library functions supplied (IBM PC version).
   
       -   All source code for compiler, libraries and utilities is included.
   
       -   Includes code generators for: 8080/8085/Z80, 80x86, 6809, 68HC11
   
       -   80x86 implementation is MASM compatible and supports both the TINY
           and SMALL memory models.
   
       -   More complete implementation, more efficent code produced,
           and faster compilation than most other "SMALL-C" compilers.
                        *** MICRO-C Language Summary ***
   
       It does support:
   
           - All 'C' statements:
               if/else     while   do/while    for     break   continue
               return      goto    switch/case/default {}      ;
   
           - All 'C' operators:
             (Except structure reference: . and ->)
               +   -   *   /   %   &   |   ^   <<  >>  >   <   ==  ~
               +=  -=  *=  /=  %=  &=  |=  ^=  <<= >>= >=  <=  !=  !
               ++  --  ?:  ,   ()  []
             (++ and -- may be pre or post)
             ( * and &  also perform INDIRECTION and ADDRESS OF)
   
           - The following data types (with no restrictions):
               int         char        unsigned    (incl: unsigned char)
               extern      static      register
                   - pointers to any type (including pointers)
                   - Arrays of any type (including pointers)
                   - Function can return any type (incl. pointers)
                   - Typecast of value to above types
   
           - Multi-dimensional arrays.
   
           - Decimal, Octal and Hex constants
               eg: 127, 0177, 0x7f
   
           - Inline assembly code
   
           - Full support for strings and character constants: ('' "")
               Including:  \n      Newline
                           \r      Carriage return
                           \t      Horizontal tab
                           \b      Backspace
                           \f      Formfeed
                           \177    Octal constants
                           \x7f    Hexidecimal constants
             (16 bit character constants are supported. eg: 'ab')
   
           - Fairly complete preprocessor
             - Integral pre-processor is very FAST and supports
                 #define       (non-parameterized)
                 #include
                 #ifdef/#ifndef/#else/#endif (single level)
                 #asm/#endasm
             - External pre-processor supports:
                 #define       (fully parameterized)
                 #undef
                 #forget       (multi undef -similar to forth forget)
                 #include      (with <> library support)
                 #ifdef/#ifndef/#else/#endif   (fully nested)
                 #asm/#endasm  (passed through & handled by integral)
   
       It does not support:
   
           - Structures and Unions, Typedef, Long / Double / Float and
             Enumerated data types, Bit fields.
