Syntax	addr (reference)
Description	The addr attribute is used to find the integer address of a variable or non scalar constant. This is implementation-dependent. This address may be used in an indirection operation @.
Example	Set a to be the address of x. var x : real var a : addressint := addr (x)
Details	The value of the address produced by addr is of type addressint, an integer type whose range is that of the underlying memory addresses. The concept of an address is implementation-dependent. For example, an optimizing compiler could determine that a variable does not require space because the program could be computed without the variable with no change in output. However, in most implementations, types have a predictable size and variables of that type occupy that number of bytes in memory.
