The Squeak virtual machine is software that acts as an interface between Squeak code and the microprocessor. The Squeak virtual machine is written in Slang, a functional subset of Smalltalk that can be translated into standard C. Squeak essentially uses the C language as a cross-platform equivalent of assembly language. Since Slang is a subset of Smalltalk, the Squeak virtual machine can be edited and debugged by running it in Squeak itself. The virtual machine can also be extended with plug-ins, written in either C or Slang. These are used in Squeak for such things as playing MPEGs and for Squeak’s built in public key encryption abilities.
