Commands that elude me

[Rick]

editingmission - Probably a variable signifying a mission is being edited (Graal3D probably).
waterheight - Graal3D water probably.
getsurfacetype - Graal3D.
popdialog() - Popping a dialog from the stack. Think a layer of cards on which you remove/add cards. Now think of this as GUI windows instead.
pushdialog(obj) - Pushing a dialog onto the stack. See above note.
selectedsword - Graal3D probably.
commandtoserver(str) - Graal3D.
extractfilebase(str) - extractfilebase("directory/file.txt") will return "directory" (or "directory/" ?).
findfirstfile(str) - Iterating through lists of files, removed in v4 I believe.
findnextfile(str) - See above note.
getboxcenter(str) - Graal3D, I assume it returns a vector of the center of a 3D box.
getdatablocktypes() - Graal3D.
getobjectbyray(str, str) - Raycash check for objects. Graal3D.
lightscene() - Graal3D, tells the client to generate a lightmap for the current mission.
mapshapeanimation(str, str, str, float) - Graal3D.
triggerserver(str, str, str) - Just like triggeraction without coords and serverside parameter.

Stuff I can identify is above...
