Doors.NET Reference Manual

- 471 -

NOTE: This example uses Boolean Arithmetic. Please be familiar with Boolean Arith-

metic before attempting to program this type of macro. Note the ! symbol in front of the

Global Lock and Global Unlock trigger variables. This means that this trigger will only

execute if both Global Lock and Global Unlock are False. The ! is a Boolean variable rep-

resenting the NOT (or inverse) so we have NOT False AND NOT False which is the

same as TRUE AND TRUE. So if either one is true then we have a NOT TRUE and

therefore the trigger will not execute.

The Global Lock and Global Unlock trigger variables can also be used individually as

part of a trigger macro to have the controller perform certain events (like a door forced

open or held open) differently when either of these are in effect. In this case configure the

trigger without the ! and define the rest of the trigger.
