	Description: Simulation of an assembler with an output in unique 8 base encoding.
	Input : File names to convert without .as extensions
	Output :  1) Syntax Errors and their location in the .as file
		  2) For valid file we will create several files with the following extensions:
			- .ob: encoded operation for linker
			- .ext: memory address of external variable
			- .ent: memory address of the labels
