Read/Write Variables

Read/write variables (RWV) are the same as the variables of conventional languages. As the name implied, the value of a RWV can be assigned and examined by the user. For instance,

A = 1

will assign integer 1 to the RWV A. The value of a variable is referenced if the variable appears in an expression - e.g. the right-hand side of the assignment statement. For example,

B = A

puts the value of A into RWV B.

Note that, in EDEN, a function is considered as a RWV (although there is a different instruction to define a function, and some restrictions on their definition). Functions will be discussed in the later chapters.
