Used to force string concatenation of two expressions.
result = expression1 & expression2
The & operator syntax has these parts:
| Part | Description |
|---|---|
| result | Any numeric value. |
| 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.
