& operator

Used to force string concatenation of two expressions.


result = expression1 & expression2

The & operator syntax has these parts:

Part Description
result Required; any String or Variant variable.
expression1 Required; any expression.
expression2 Required; any expression.


If an expression is not a string, it is converted to a String variant. The data type of result is String if both expressions are string expressions; otherwise, result is a String variant.

If both expressions are Null, result is 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.


This example uses the & operator to force string concatenation.

Dim MyStr
MyStr = "Hello" & " World"   ' Returns "Hello World".
MyStr = "Check " & 123 & " Check"   ' Returns "Check 123 Check".
