TEXT:00,We mentioned previously that a program will store
TEXT:16,data for analysis. Your computer's memory (RAM) best
TEXT:16,resembles a huge group of mail boxes, each of which
TEXT:16,is uniquely addressed by a number. Each of these
TEXT:16,storage locations can hold a value between 0 and
TEXT:16,255. Each of these values is referred to as a
TEXT:16,"byte". If values over 255 need to be stored
TEXT:16,in RAM, it is split up between various locations.
TEXT:16,While data is always stored as numbers in RAM,
TEXT:16,it can be both numeric or characters like "A".

TEXT:32,To write a program that accesses RAM locations by address number would
TEXT:16,be tedious, especially when dealing with large data values. Thankfully,
TEXT:16,Euphoria offers a way to access stored data in RAM not by the actual
TEXT:16,RAM address number, but by a label like "salary" or "points". This
TEXT:16,symbolically referenced memory location is called a "variable".
