An Example of a GREET_PROG or ALL_GREET_PROG

1) Type: GREET_PROG or ALL_GREET_PROG
2) Args: 100
3) Commands

the room.
the room and the creature with this PROG is not fighting.

A GREET_PROG is the same as an ALL_GREET_PROG except that it
adds another condition to this.  The GREET_PROG only triggers
when it can 'see' the player or creature entering.

If you don't know what ARGS is, help args.

First, the player or creature enters the same room as the mobile.
The mobile makes a random roll and if this random roll is less
than ARGS value, then the trigger occurs.
Note: GREET_PROG checks that it also can see the 'player' or
'mob' entering the room.  (if it can't see, it won't execute
either.)
