Operators and expressions

The string operators are shown in the table below.

Table 1. Arithmetic operators

Operator	Operation
+	Concatenate

You can write a string expression containing multiple concatenations. The following examples use the string representation required for the advanced format (see Representation of strings and special characters, treatment of operator characters).

Expression:               Evaluates to:

'Hello ' + 'Fred' + '!'   'Hello Fred!'
'Hi' 'There'              (Error, a + operator is required to concatenate strings)
'Hi' + 'There'            'HiThere'
