                   ** Common Questions and Answers **

Q: Is MICRO-C a full ANSI compiler?

    No, MICRO-C is a "subset" compiler. It does however, support much more
    of the 'C' language than most other subset compilers, including:
      - All 'C' statements:
        if/else     while   do/while    for     break   continue
        return      goto    switch/case/default {}      ;       asm
      - All 'C' operators:
        +  -  *  /  %  &  |  ^  <<  >>  >  <  == ~ ++ -- ?: , . ->
        += -= *= /= %= &= |= ^= <<= >>= >= <= != ! () [] sizeof
      - The following data types:
        int     char    unsigned    (including: unsigned char)
        struct  union   extern  static  register
        *(pointer to any type, incl. pointers and structs)
        - Arrays of any type (incl. multi-dimension, pointers & structs)
        - Function can return any type
        - Typecast of values to other types
      - Decimal, Octal and Hex constants. eg: 127, 0177, 0x7f
      - Full support for strings and character constants: ('' "")
        Including: \n \r \t \b \f \177(Octal) \x7F(Hex)
        (16 bit character constants are supported. eg: 'ab')
      - Inline assembly code (single or multi statement).
      - Preprocessor commands:
        #define     (fully parameterized & multi-line)
        #undef
        #forget     (multi undef -similar to FORTH forget)
        #include
        #ifdef/#ifndef/#else/#endif (fully nested)
        #file       (sets filename displayed in error messages)
      - It DOES NOT support:
        Typedef, Long* / Double / Float / Enumerated data types, Bit fields.
      * 32 bit "long" number math functions are provided in the library.
        These may be easily adjusted to manipulate even larger numbers.
        (8051 Compiler includes a floating point library)

Q: Is MICRO-C just another version of SMALL-C?

    No, MICRO-C is a completely new design, with several advantages:
      - Supports more of the 'C' language: structs & unions, unsigned int
        & char, pointers to pointers, arrays of pointers, multi-dim arrays,
        typecasting, sizeof, parameterized and multi-line defines ...
      - Much more efficent code generated, much faster compilation.
      - More portable: MICRO-C was designed to support many CPU architectures.

Q: Does MICRO-C run on a (Macintosh, UNIX box, etc...)?

    At the present time, all of our official products run on the IBM PC
    under DOS or a DOS compatible operating system. We may be able to
    provide un-official ports to other platforms, however technical support
    will be minimal. Contact us for more information.

Q: Does MICRO-C output assembly code?  Do I need an assembler?

    MICRO-C generates assembly code. All developers kits include our XASM
    cross assembler, which our IDE and CC commands automatically run for you,
    giving you a "one step" compile.  A command option allows you to include
    the 'C' source code as comments in the ASM listing.

Q: Does MICRO-C support the (insert favorite processor)?

    See the CATALOG for a list of processors which we directly support.
    We have application notes on adapting the compiler to use with CPU
    variants (such as extra registers/ports or differing memory maps).

    If you need support for a different processor, please check with us.
    We may be planning a release for the processor you want (or perhaps
    you can "convince" us that is would be a good idea).

Q: How much code can I fit in (nK) of memory?

    That depends on so many factors that its impossible to give you a general
    answer. It is usually more that you would think, because MICRO-C produces
    fairly compact code. This is especially true with our "Developers Kits",
    because their libraries are hand-coded in assembly language, using very
    tight code. Here are some examples of appications:

    MICRO-C Compiler (compiled itself!)                     23K
    ANSI terminal with built in XMODEM file transfer        10K
    Combination lock (rotary encoder, led indicator)        2K
    Telephone "distinctive ring" switcher (1 - 3 lines)     1.5K

Q: Is your EMILY52 simulator really that fast?

    EMILY's speed is dependant on your PC (>150,000 inst/sec on 386/25,
    >500,000 inst/sec on 486/33).

    My tests have shown EMILY on the 386/25 to be roughly equivalent to a
    4Mhz 8052. For example, a customer reported that an algorithm he had
    calculated would take about 1 second on a 12Mhz 8052 took 3 seconds
    under EMILY. In contrast, the same program took over 20 MINITES when
    run with another popular simulator.

Q: Is MICRO-C really as good as you say it is?

    Sturgeons Rule has it that 90% of science fiction is junk. A similar
    rule applies to PC software, but I'd say that 90% is a lower bound.
    Once in a while, though, you find a product that makes up for the rest..
    If price has kept you out of the microcontroller C market, you have no
    further excuses. Micro-C is as good as it gets!
                                    - Circuit Celler INK Dec91/Jan92

    I just obtained Micro C, and I'm very impressed!...
    The portability of Micro C is second-to-none, as is it's professionally
    written code and overall usability... I need to emphasize here that
    Micro C is by far the best coded compiler I've ever seen. This excellent
    code quality extends throughout all associated modules.
                                    - FIDOnet 'C' programmers echo

    Dave, Thanks for responding to the minor problem I had with your
    wonderful little compiler.
