Purpose

Used to force string concatenation of two expressions.

Syntax

expression1 & expression2

Description

Whenever an expression is not a string, it is converted to a String subtype. If both expressions are Null, then the result is also Null. However, if only one expression is Null, that expression is treated as a zero-length string ("") when concatenated with the other expression. Any expression that is empty is also treated as a zero-length string.
