== Introduction == RS String is a codename for a custom string data-type used in the RuneScape protocol.
The string data-type is used to hold a series of characters in order to form a message. ===Old Engine Protocol=== In the old engine client, the RS String datatype is delimited by a newline character (value "\n"). ===New Engine Protocol=== In the new-engine client, the RS String datatype is delimited by a null byte (value 0).
