Concatenation (&)

This operator is used to force string concatenation of two expressions.

Syntax

result = expression1 & expression2

Parameters

result

Any numeric value.

expression1

Any expression.

expression2

Any expression.

Remarks

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 also is treated as a zero-length string.
