Hi.
While editing the original A&A maps, I found several things that have undefined numbers in the current Doom Builder Config File (2-Feb-2014).
I have tested the maps (actually only Q1M1) with and without those objects, and I found what are they used for.
Most of them are markers like in Duke3D, that will transform the sector into something different, or ambience sounds, etc, but others seem to have some unknown effect that after testing the map with and without them, nothing seems to change.
I marked those markers with a "Unknown action" label.
I'm quite lazy to add them to the Doom Builder config file now, so if anyone is not that lazy can add them hehehe
I will use Doom nomenclature, for example "DR Open Wait Close" means "Door Repeatable Opens, Waits a bit and automatically closes".
Actually only tested from Q1M1, so there may be others differents in another maps.
List Updated: 4 - Feb - 2014.
IMPORTANT NOTE: Markers that doesn't appear in this list, may not exists. If this is the case, the game will crash when the map loads.
Updated markers will be marked with a "=>" instead of a "?"

* For 1500: this marker lowers the marked sector's ceiling to the floor and allows it to be opened by pressing "use button, open door" key. You don't need to "close" the door in the map editor because the game will do this automatically.
* For 1518: the thing tag/value/attribute tells the engige what level goes next.
