where ²SirenOn² denotes the output statename. Executing ²SirenOn² in the path command will send

a positive pulse train to PB0 and send a logic low to PB1.

Path command definition

Syntax:

PATHS

pathname: path command ....

The pathname is defined according to the user¢s desire. The elements of the path command are listed
