+ParaPascal interpreter can simulate any number of processors. The picture above shows a configurations with 6 processors.
 
 Parapascal programs consists of list of object that represent instructions - [Command pattern] [1].
 This is much faster than bytecode interpretation since there is no instruction decoding stage.

 This is the environment in which parapascal programs are executed. Interpreter has several distinct elements:
 
 * Kernel - provides system functions and process scheduling
 * Processors(1..*) - no general purpose registers, zero and one addressing instructions, stack based.
 * Private Memory - each processor has one separate memory model just for itself. 
 * Shared Memory - only one processor can use shared memory at a time (global lock).

 Translates textual representation of instructions into form sutable for interpretation.
