assembly - 如何修复宏中的 "Expecting pointer type"和 "symbol already different kind"

Question

我不确定我做错了什么。

我试过在宏中添加前缀@@以及在宏中声明本地@@label，但没有用。

我也查看了这个网站 link以及之前的问题中提到的......它没有用。

在 DOSBox 中，我一直收到错误“预期的指针类型”和“符号已经不同种类”，但在 emu8086 中，没有任何问题。

LOCAL 指令必须位于宏的最开头。宏声明和 LOCAL 行之间的空行已经太多了。它应该看起来像这样:

draw_box_outline macro x_fin,y_fin,x_ini,y_ini
local col_draw,row_draw,row_rev,col_rev

另外，请看这里:TASM; LOCAL and LOCALS directives .
