I've been fiddling with around with DM for a while now but I still haven't learned much about Datum's yet. Could someone explain to me and give me an example?

A datum is an object that lacks most of the vars, except for type and parent_type (although it can be "moved" to someone's contents, it doesn't have a loc). It also lacks most of the procs, only having New(), Del(), Read(), Write(), and Topic(). It is useful for holding abstract concepts, such as teams and skills.

Most of this is correct. However, I get "runtime error: cannot append to list" when I try to put a datum, text or num in something's contents. According to the helpfiles, the contents list is for movables (mobs and objs) and, in the case of areas, turfs. However, if Santa delivered a programming trick to work around list instance limits, I'm all ears. =)

Oops! You're right. I thought I remembered having datums in contents, but that was just another list I created to hold datums. My bad.
