Concatenation Operator (&)

Forces string concatenation of two expressions.

result = expression1 & expression2

result

Any variable.

expression1

Any expression.

expression2

Any expression.

Whenever an expression is not a string, it is converted to a String subtype. If both expressions are Null, 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.
