Abstract: WCC is a small, experimental compiler for a functional subset of the C programming language. The current implementation of the compiler generates code for the VAX-11 computer running either the VMS or the ULTRIX operating system. The WCC compiler itself is written in C (maybe one day it will be able to compile itself).

Program Control

• if (expression) statement
• if (expression) statement else statement
• while (expression) statement
• break
• continue
• return

Data types

• char
• short
• int
• long
• float

One dimensional arrays of these primitive types are allowed, pointers to these types are allowed. No complex types are implemented. All arithmetic operators are implemented except bit manipulation. Function calls are supported.
