# 2.1.10 Block

A block is created by first selecting the track segments in the block and then selecting Create Block from either the Add menu Section 3.3.1 or from the block menu on the hotbar. A block gets a name and a script. The name is only used for identification and the script is used by the layout control software. The script should provide whatever information is needed by the layout control software to determine block occupancy. This could be a code snippet to retrieve the state of the block occupancy or it could be the address of the sensor, etc.

The create block dialog has spaces for two text strings. One is the name and the other is a block occupancy script. The name identifies the block and the script is information used by the layout control software to detect block occupancy. The script could be a code snippet or I/O device address information, etc.
