Author: John San Diego COS 331 operating system Project 1 - PBrain12 Interpreter Version 1.00 - 09/29/2016

To compile: gcc Interpreter.c -o Interpreter.out

Brief: The Interpreter for PBrain12 Operating system. The Interpreter consists of the following variables IR = Instruction Register - 6 element character array which hold the instructions P0-P3 = pointer registers R0-R3 = program registers PC = program counter PSW[2] = program status word - character that can be either T or F memory = is the character 2d array where process and IR is stored

There are 9 helper functions which supports all of the operand functions -ParseOp1 - returns IR[2] and IR[3] -ParseOp2 - returns IR[4] and IR[5] -ParseOp1Reg - returns IR[3] -ParseOp2Reg - returns IR[5] -ParseOP1andOP2Imm - returns IR[2-5] -PrintIR - returns Instruction registers -FetchData - returns whats in a specific memory location -printMEM - returns all in memory -setMEM - converts Accumulator to character and store it in index specified in
memory.

There are 35 Operand functions start from OP0 - OP35

Bug: Currently, I haven't found any bugs using the Fibonacci, if and else, and the for loop.
