Description

Constant: string EOF = "\n\n\n";

The string constant EOF has the value "\n\n\n"

EOF is a value returned by the dataserver event, as a result of a call to llGetNotecardLine, specifically when the requested line is past the end of the notecard. The value returned equals "\n\n\n", which is to say, three newline characters (0x0a).

Essentially, it is used to let you know when you have finished reading information (usually user configurable parameters) from a notecard, and are ready to move onto the next stage or state of the script.
