ACC (programming language)

ACC is a near-C compiler for the MS-DOS operating system on the IBM PC line of computers for programs. The compiler and compiled programs will run on any Intel 80386 or above PC running MS-DOS. Included with the compiler are a 386 assembler and a linker for combining multiple object files. There are also two libraries, which are a protected mode DOS extender (based on Thomas Pytel's, AKA Tran's PMODE30B + PMODE307 DOS extenders), and a library of functions callable by C programs.

Pointers are 4 bytes, and can access all available memory. All memory can be allocated too. The compiler, assembler and linker are all very small and reportedly very fast.
