算了，我来回答，本来很简单的问题，搞出这么多的花样。以下是直接从masm 6.1文档摘录出来的：
Use two at signs (
) followed by a colon (:) as an anonymous label. To jump to the nearest preceding anonymous label, use @B (back) in the jump instruction’s operand field; to jump to the nearest following anonymous label, use @F (forward) in the operand field.
The jump in the following example targets an anonymous label:
jge @F
.
.
.:
The items @B and @F always refer to the nearest occurrences of
:, so there is never any conflict between different anonymous labels.
