There is a special operator that can be used with strings, which is the concatenation operator. This is the & symbol which if used is used to join two or more strings together:
a="1234";
b="567";
c=a & b & "89"; // c becomes "123456789"
The result above is that the variable c will be set to “123456789” which is a concatenation of the strings stored in variable a and b and the string constant “89”.
