Line 117:
Addresses in the thread are the addresses of machine language. This form is simple, but may have overheads because the thread consists only of machine addresses, so all further parameters must be loaded indirectly from memory. Some Forth systems produce direct-threaded code. On many machines direct-threading is faster than subroutine threading (see reference below).
An example of a [[stack machine]] might execute the sequence "push A, push B, add". That might be translated to the following thread and routines, where <code>ip</code> is initialized to the address labeled <code>thread</code> (i.e., the address where <code>&pushA</code> is stored).
