SUMMARY
=======

The Microsoft Macro Assembler (MASM) 5.1 and later provides a way to generate
anonymous labels for jump instructions. To define the local label to be jumped
to, use two at signs (@@) followed by a colon (:). The operand used in the jump
instruction can be one of the following

  @B (back)
  @F (forward)

The @B will jump to the previous local label and the @F will jump to the next
local label.

MORE INFORMATION
================

The fragment below illustrates this feature:

      cmp ax,cx
      jge @F
      .
      .
      .
  @@:
      .
      .
      .
      jle @B

The jump to @F will jump to @@: and the jump to @B will jump back to the @@.
