@SETBLOCK <var:$Obj<playername>.BlockType>:<var:$Obj<playername>.BlockData> $Obj<playername>.Position
This plain won't work.

After much more complex scripting, I fins that the actual issue that this problem may be tied to is much broader than setting block data. I find that when VT parses a command line for a <var:> and converts the first one, it stops looking for any more, thus leaving the second one unprocessed. This also holds implications for when an attempt to use a <var:> on both an object name and the variable name attached to that object is needed to pro grammatically set up the $obj.var's name.
