Hmmm... just took a look at the program now. This is set up for use with story sequences, etc. (might be able to adapt it for simplistic normal board walking, but could be tricky...).
Although I didn't test it, it looks like the commands work like this:
#newobjectpos(objectname$,pose$,tile1$,tile2$,tile3$,tile4$)
This assigns a pose to a sprite.
objectname$ - the name of the sprite
pose$ - the name of the pose
tile1-4$ - the four tiles associated with the pose
#setobject(objectname$,tilex!,tiley!,tilelayer!,pose$)
Set the sprite objectname$ on the board at position (tilex!,tiley!,tilelayer!) with pose pose$.
#eraseobject(objectname$)
Erases the sprite objectname$ from the board.
The rest of the program (the beginning to the first #method) is an example of how to use it.
