I create a print function in assembly for this. When i try to print '----' with this. it does not work. My code is available on this url: ThunderEagle/printf.asm at master · Sansoft500/ThunderEagle · GitHub[^] please help me to solveWhat I have tried:The url is shown before is the only but when i use mov al,'-'int 10hint 10hint 10hit works. how i use this with my function?printf:mov ah,0x0emov bh,0x00mov bl,0x07next:mov al,[si]or al,aljz doneint 0x10inc sijmp nextdone:ret 推荐答案 要使用BIOS中断10h打印字符，首先必须在AH中设置该功能... To print a character using BIOS interrupt 10h, you first have to set the function in AH...mov ah, 0x0emov al, '-'int 0x10 如果您希望我们检查您的代码，请将其粘贴到您的代码中问题而不是添加链接... If you wish us to examine your code, please paste it in to your question instead of adding a link... 来自GitHub网址的代码： Code from the GitHub URL:printf:mov ah,0x0emov bh,0x00mov bl,0x07next:mov al,[si]or al,aljz doneint 0x10inc sijmp nextdone:ret 以上要求 DS：SI 指向空终止字符串。所以你需要这样的东西： The above requires that DS:SI is pointing to a null terminated string. So you need something like this: SECTION .dataminus3: db "---", 0 SECTION .TEXT; ...; DS must be .data which it usually is mov si,minus3 call printf 这篇关于打印签到装配的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
