	Note: The length of a pascal string is stored as the first byte.
		  A pascal string does not have a termination byte.
		  A pascal string can hold at most 255 bytes of data.
		  The first character in a pascal string is offset one byte from the start of the string. 
		  
		  A C string is terminated with a byte of value zero.  
		  A C string has no length limitation.
		  The first character in a C string is the zeroth byte of the string.
