Small C Compiler Version 2.2
                                         
         The  Small C compiler translates a subset of the C language into
         assembly language. It runs under PC/MS-DOS 2.1 and later.  Small
         C  is  compatible  with  the Microsoft and Small Mac assemblers.
         Small C takes full advantage of the ability of these  assemblers
         to  generate  relocatable  object code, to maintain libraries of
         relocatable modules, and to  link  separately  compiled  program
         modules.  It supports a small memory model with one code and one
         data/stack segment.
         
         Small C supports  arrays  of  one  dimension.  Functions  always
         return  integer  values.  External  functions  are automatically
         declared. Initialization of global variables is  supported.  The
         preprocessor supports #include, #define, #ifdef, #ifndef, #else,
         #endif,   #asm,   #endasm   commands  .  The  following  control
         statements are supported:  if,  switch,  case,  default,  break,
         continue, while, for, and do/while. All expression operators are
         supported.  Only  signed and unsigned integer and character data
         types are supported. The following standard C features  are  not
         supported:  structures,  fields, unions, arrays of pointers, and
         casts.
         
         Small C supports  UNIX-like  I/O  redirection  and  command-line
         argument passing. The Small C library includes over 80 functions
         --  a  nearly  complete  set  of the standard UNIX/C repertoire.
         Binary as  well  as  character  stream  I/O  is  supported.  The
         formatted  I/O  functions  printf()  and  scanf()  are included.
         Random  access  to  files  is  provided.  Programs  can  request
         additional file buffering.
         
         The  compiler  itself  is  written in Small C and is distributed
         with both object and source code. As a self  compiler,  Small  C
         can  be  modified  to  work  in  other  environments and to meet
         special  needs.  Since  everything   is   revealed   and   fully
         documented,  Small  C  has  tremendous  value  as an educational
         device. Small C uses a single pass,  recursive  descent  parsing
         algorithm.  It generates p-codes for internal use, and optimizes
         its output.
         
         The Small C language and compiler  are  fully  described  in  "A
         Small  C Compiler: Language, Usage, Theory, and Design" by James
         E. Hendrix. Copies are available from:

         An older CP/M version of the compiler is  also  available.  That
         version  is  documented in "The Small-C Handbook" which does not
         cover the theory of operation. The Handbook  is  also  available
         from M&T Publishing, as long as supplies last.
