created. Then fcb.lhaddr will already be set to the TCB address of the
LINE^HANDLER task.
In the following cases, the FCB of the receiving task is obtained by calling
GET^ITC^FCB once:

•
A DEVICE^HANDLER task is sending a message to another
DEVICE^HANDLER task
•
A LINE^HANDLER task is sending a message to a DEVICE^HANDLER task
•
A LINE^HANDLER task is sending a message to another LINE^HANDLER
task
The FCB returned by GET^ITC^FCB is used for fcb in subsequent calls to
SEND^ITC^MSG[X] to send a message to the receiving task.
