there is not a single command in tcl, if i remember correctly.
but you can unset variables and arrays. they are also
cleaned up when used locally in a subroutine.

the most memory loss in VMD is usually due to trajectory
data (you can delete molecules to free that) and from
creating selections without deleting them.
 
other than that, it is easier to exit VMD and start over.

do you have a specific problem or can you describe a
scenario where something akin to 'clear' would be
desirable?

cheers,
