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 both Small Assembler and the Microsoft
assembler MASM. Small C 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:
