what does itmGetImageDesc, scrGetListEntry return and can it be used in game?
what does link, scrRefreshItemListCursor do?
what does objCanAttack mean? I know you can still return true if the ship doesn't have any weapons.
What does the filter in sysVectorRandom mean exactly?
What does the last argument in lnkAppend do?

the obj*Identified functions is also giving us problems

We tried objClearIdentified then objIsIdentified for an object on the origin (we where not near there) and both returned true.
