Conditional jump out of range in 8086 assembly

Question

I'm coding in assembly for Intel 8086 under TASM in DosBox and the problem I frequently stumble upon is getting the compilation error of "Relative jump out of range by some bytes" where my conditional jumps are.

Now, I know that conditional jumps are short jumps but is there any way to somehow... "stretch" them? :) I know I can place intermediate jumps or try to assemble the code so that the jumps are in reach but as my program grows larger, I think the latter option may prove to be less valid than now.

Can I somehow tell the compiler to make something with it or can I somehow tweak my jumps?

Answer 1

自从我完成任何汇编编码以来已经有很长时间了，但是正如我回想的那样，“拉伸”条件跳转的通常方法是反转测试的逻辑，并放置一个绝对跳转来表示您要采用的分支有条件的跳跃之后。

Answer 2

Another way was to put a "table" of jumps within reach, then you relative jumped to to the jump you wanted to jump to. :)

You could get clever with that and change the jump in the table. Course debugging such code was 'erm "fun"..
