Description
Constant: string EOF = "\n\n\n";The string constant EOF has the value "\n\n\n"
EOF stands for "End Of File". It is a value returned in SL by the dataserver event, as a result of a call to llGetNotecardLine. It is returned when the end of text in the notecard has been reached. 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 state or stage of the script.
