汇编语言中的@和$是什么意思啊？

@@是标号，pop ebx这条指令的标号
比如需要跳转到这条指令时，可以用LJMP @@或SJMP @@
@b是指间接地址

楼主给出的汇编语言，是80x86系列CPU的32位的汇编语言。
楼上，回答者 yyh001123 解释的汇编：LJMP、SJMP，是单片机8031的汇编语言。
俩人说的不是一档子事。

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.
