Separating the data and return stacks in a machine eliminates a great deal of stack management code, substantially reducing the size of the threaded code. The dual-stack principle was originated three times independently: for Burroughs computers, Forth and [[PostScript]]), and is used in some Java virtual machines.

Three [[processor register|registers]] are often present in a threaded virtual machine. Another one exists for passing data between [[subroutine|subroutines]] ('words'). These are:
