Animation of limb based objects is pretty straightforward, especially as you sound like you know DBC. Use the "Rotate Limb", "Scale Limb" and "Offset Limb" to move a limb, resize it (great for making a character breathe) or reposition it. Once you've got the limbs in the right position, use "Set Object Keyframe" to lock the particular frame. You can then reposition the limbs for the next keyframe. You needn't animate every single frame, DBC and DBpro will automatically generate the necessary "inbetween" frames.
Unfortunately, the Save Object Animation command was removed from DBPro "to make way for future enhancments". To my knowledge (which I admit is a bit limited when it comes to DBPro), it's never been reintroduced and the enhancments never materialised.
I think if you look under the "Getting started" section in the DBPro help files, you'll find an entry called "Migrating from DarkBasic 1.0". I may be mistaken as to its location, but the file is there and it'll tell you which commands have been removed from DBC for DBPro because of redundancy.
It is said there are 10 types of people in this world - those who understand binary, and those who have friends!
