Surface Symbol Type


The surface symbol type is used to store the reference number of a surface. If the surface's value is passed from a JKL, any messages generated by the surface will be received by the cog. Syntax:
surface     surf1     local

Or if the surface's value is passed from a JKL, don't use the local extension:

surface     surf1

Mask Info: Surfaces can send two messages: entered and crossed. Giving the surface Mask Flags controls what things can generate these messages.
