loading and animating a mesh?

Noobish yet very necesary question ;]
Once I have loaded a mesh with the LoadAnimMesh function, how do I animate it?
ie. If it was a walk cycle, make it go through the frames and then loop back to the beginning again?
And what does SetAnimKey do, exactly...?
Can anyone help me?

i dont understand these animated meshes much, but as i understand it, you use Animate mesh, 1
Animate [mesh your using], [looped]

Still not working...
Do I put this in the main loop or what?

In addition to using the Animate command, make sure to call UpdateWorld every frame. The animation is only incremented on UpdateWorld.

does your Animated Mesh have any actual movement? IE KeyFrames?

But the animate command does not have to be in the loop.

For example

obj1=LoadAnimMesh("D:\4x\crap1.x")
PositionEntity obj1,67,17,10
ScaleEntity obj1,5,5,5
EntityType obj1,2
EntityRadius obj1,2
EntityAlpha obj1,1.0
EntityBlend obj1,1
Animate obj1,1,.4
While Not Keyhit(1)
UpdateWorld
RenderWorld
