X86 程序集 我想从键盘上获取一个数字并进行比较，之后我想打印一条消息

Question

我想从键盘上获取一个数字并进行比较，然后我想打印一条消息。这是我的代码...

我的问题：当我从键盘上得到一些东西时，我可以按任何键，它仍然说"PC：Salut"。程序运行时无需比较。我想按 1 和程序知道 1 个带Romana_Salut的 corespunds。

它用tasm（masm）和DOSBox中的链接进行测试。.....................................................................................................................................................................

我进行了编辑，使其与我对程序的意图相匹配。
