                          * The MICRO-C 2.0 Compiler *
    
       MICRO-C is a tiny compiler for the 'C' language. It has been designed
    to be VERY portable, and can be moved between different  processors  and
    operating systems with little difficulty.
    
       MICRO-C should not be compared to MICROSOFT, TURBO,  or  any  of  the
    other P.C. compilers, because it it intended for en  entirely  different
    purpose. These are very good compilers, but they are  large,  expensive,
    and dedicated to specific computer environments. MICRO-C is tiny (it can
    be made to run in less that 32K), and allows you to take it anywhere you
    want.
    
       The complete MICRO-C package includes all  source  code  and  support
    files you need to port the compiler to any environment. It also includes
    code  generators  for  the  6809,  68HC11,   8080/8085/Z80   and   80x86
    processors. With this package you can turn out an "instant" compiler for
    any machine using one of those processors. The documentation  file  also
    contains detailed information on writing new code generators  for  other
    processors.
    
       MICRO-C is also  an  excellent  learning  tool.  Not  only  does  the
    complete, well documented source code for  the  compiler  and  utilities
    give you the opportunity to explore and understand those  programs,  the
    source code for the library gives you information on all kinds of system
    programming, such as:
    
                - DOS and BIOS services
                - Video screen and windowing functions
                - Interrupt driven serial communications
                - Terminate and Stay Resident (TSR)
                - Lots MORE (Over 130 functions)
    
       For more information on the compiler, see the file MC.DOC. This  file
    is quite large, make sure you are in no hurry before printing  it  on  a
    slow printer. The table of contents pages are printed last,  and  should
    be inserted between the title page and page 1.
    
       Version 2.0 of MICRO-C represents many code  improvments,  bug  fix's
    and added  capabilities.  It  is  no  longer  "User  supported  Software
    (shareware)", due to lack of  user  support.  This  archive  contains  a
    "DEMO" package, consisting of the IBM PC executables and support  files.
    If you like what you see, and wish to obtain the complete  package  with
    source code for the compiler, libraries  and  utilities,  Fill  out  the
    order form at the end of this document,  and  send  it  along  with  the
    required payment to:

       If you decide not to order the complete  MICRO-C  package,  you  MUST
    discontinue using MICRO-C within thirty days.
    
       Permission is granted to copy and distribute this  archive,  provided
    that it is kept in its original form, with no modifications of any kind.
    
                              * Getting Started *
    
       To install MICRO-C on a hard drive, simply  create  a  directory  and
    unpack this archive into it. The directory  "\MC"  is  preferred,  since
    some of the utilities assume this is the MICRO-C home  directory  unless
    told otherwise.
    
       Once you have installed the system, refer  to  the  section  entitled
    "THE COMMAND CO-ORDINATOR" in the MC.DOC file for information on how  to
    compile programs using the 'CC' command. You should either  include  the
    MICRO-C directory "\MC" in your PATH, or  copy  the  CC.COM  file  to  a
    directory which is already in your PATH. Also, make sure that  the  MASM
    and LINK commands are available on your  system.  The  MCDIR  and  MCTMP
    environment variables should be set up  as  described  in  the  document
    before attempting to use CC.
    
       Once you have everything set up, you may wish to try  compiling  some
    of the example programs which are included in this archive.
    
                            * MICRO-C under MS-DOS *
                            * Implementation notes *
    
       The 8086/MS-DOS implementation of the compiler produces code for  the
    Microsoft MASM (or compatible) assembler in either  the  TINY  or  SMALL
    models. It has been tested with MASM 4.0, MASM 5.1  and  TASM  1.0.  The
    LINK utility is required to create a ".EXE"  file.  NOTE  that  programs
    produced for the TINY model will execute as ".EXE" files,  however,  due
    to PSP being outside of the data/code segment, command  line  parameters
    are only available when the program is converted to ".COM"  format  with
    the EXE2BIN utility.
    
       The memory model to use is selected by  the  runtime  library,  which
    MUST BE FIRST in the list of object files  passed  to  the  linker.  The
    8086RL_T.OBJ file distributed with MICRO-C is configured  for  the  TINY
    model, and the 8086RL_S.OBJ file is configured for the SMALL model.
    
       The variables ARGC and ARGV (Note  capitals)  are  available  in  the
    runtime  library  module  for  use  as  EXTERNAL  references  from  your
    programs. This makes it easy for  a  function  other  than  'main()'  to
    access the programs arguments.  The  variables  PSP  and  ENV  are  also
    available to  determine  the  PROGRAM  SEGMENT  PREFIX  and  ENVIRONMENT
    segments.
    
            ie:     extern int ARGC;        /* Count of arguments */
                    extern char *ARGV[];    /* Array of ptrs to args */
                    extern int PSP;         /* PSP segment */
                    extern int ENV;         /* Environment segment */
    
       If you are using a DOS version prior to  3.0,  the  argv[0]  (program
    name) argument will not work correctly.
    
       All of the source and header files  ('.c',  and  '.h')  were  written
    using tab stops every 4 characters, which is much  more  convenient  for
    'C' development than the usual MS-DOS tab stops of every  8  characters.
    Source for a program called "type4.c" is provided, which  reads  a  file
    and displays it using  spaces  to  simulate  the  tabs  at  4  character
    intervals. To compile this program, use:
    
                                    cc type4
    
       The resulting "type4.com" file may be used to view/print  the  source
    files with proper spacing.
