Setting the parent frame when the block is first seen, instead of when it's evaluated, is what distinguishes lexical from dynamic scoping. If it's an immediate block, it's evaluated immediately, and otherwise it's pushed onto the stack. When the block is evaluated, its frame is initialized using any arguments passed to it, the next instruction's index is pushed onto the return stack, and execution moves to the first instruction in the block. When the RETN instruction is encountered, an index is popped from the return stack and execution returns to this location. As an alternative to maintaining an explicit return stack, a block can be implemented as a native function that creates a new execution stack and returns the value in it when the <strong>RETN</strong> instruction is reached. This approach uses the implementation language's call stack for the return stack.</p> <p>Local variables are manipulated with the <strong>VARO</strong> (or <strong>VARU</strong>) and <strong>VARM</strong> instructions, which load the value of a variable and a reference to it (see the next section) respectively.
