# String operators

There are two string operators. One uses the string values of the operands and return a string as result. The other one compares the operands and returns a boolean value to indicate match.

## &

String concatenation. The operation returns a text string, that consists of the two operand strings, one after another.

Example:

`'abc' 
 & 'xyz'` returns 'abcxyz'

## like

String comparison with wildcard characters. The operation returns a boolean True (-1) if the string before the operator is matched by the string after the operator. The second string may contain the wildcard characters \* (any number of arbitrary characters) or ? (one arbitrary character).

Example:

`'abc' 
 like 'a*'` returns True (-1)

`'abcd' 
 like 'a?c*'` returns True (-1)

`'abc' 
 like 'a??bc'` returns False (0)
