 === Cargo acceptance watch list (20) ===
-This property is a list of cargo types, types whose acceptance should be watched. The first byte is the length of the list, the remaining bytes identify cargo types. {{grfFrom|7}} If your GRF is version 7 or above, and has a cargo translation table, the bytes are indexes in the table; otherwise, they are cargo slot numbers. When a cargo from this list is accepted by the current tile, [[Callbacks#Watched cargo accepted (148) |callback 148]] is called on ''all'' tiles of the building. See [[Callbacks#Watched cargo accepted (148) |callback 148]] for more details about how this happens.

	To start using a house ID, you must first define it by setting its property 08 (see below). If you try to modify a house ID whose property 08 isn't set, your request is ignored, but not reported as an error, either. House IDs, unlike station IDs, need not be set in order, so you can use action 7 to skip action 0s of the houses you don't currently need (for example those houses that don't appear on the current climate anyway). You are advised to do so in order to define as few IDs as possible, leaving space for other GRFs. You don't need to skip all action 0s for a house ID to disable it; skipping the action 0 that sets property 08 is enough.
