Question

我是汇编语言编程的新手，我希望我的输出有单独的行，以便更容易阅读，但是，我编写了我的代码并让它工作，但随后被告知我不能事实上，使用Irvine程序来制作新的一行。我的教科书只使用了Irvine“Crlf”，其他人在本网站上提出类似问题的代码完全破坏了我的程序，所以现在我迷路了。

我试过的一个是：

mov ah, 0Eh       ;print new line sequence
mov al, 0Dh
int 10h
mov al, 0Ah
int 10h

无论如何，这是我的完整代码与Irvine功能仍然。有人可以帮助我获得我正在寻找的输出而不使用“调用Crlf”吗？或者让我知道为什么上面的代码破坏了我的程序？我敢肯定有一些我不知道的东西。

CRLF只是添加到输出的两个字节的序列，值为13和10.

如果你创建了一个包含这两个值的字符串，可能是import UIKit import iAd class ViewController: UIViewController, ADBannerViewDelegate, GADBannerViewDelegate { var iAdBannerView : ADBannerView = ADBannerView() var adMobBannerView : GADBannerView = GADBannerView() override func viewDidLoad() { super.viewDidLoad() loadAds() } func loadAds() { // iAd // Changed banners width to match the width of the view it is on // You need to set the y origin relative to your view. Not a static number. iAdBannerView = ADBannerView(frame: CGRectMake(0, self.view.frame.size.height - iAdBannerView.frame.height, self.view.frame.size.width, iAdBannerView.frame.height)) iAdBannerView.delegate = self view.addSubview(iAdBannerView) // Hide iAd initially iAdBannerView.alpha = 0.0 // AdMob // Changed adSize to Googles set banner size adMobBannerView.adSize = kGADAdSizeBanner // Changed banners width to match the width of the view it is on // You need to set the y origin relative to your view. Not a static number. adMobBannerView.frame = CGRectMake(0, self.view.frame.size.height - adMobBannerView.frame.height , self.view.frame.size.width, adMobBannerView.frame.height) adMobBannerView.rootViewController = self adMobBannerView.delegate = self adMobBannerView.adUnitID = "AdMobPublisherID" // Dont need var request = GADRequest() adMobBannerView.loadRequest(GADRequest()) // Do not hide AdMob initially view.addSubview(adMobBannerView) } // Use bannerViewDidLoadAd function so we know ad is fully loaded func bannerViewDidLoadAd(banner: ADBannerView!) { println("iAd has an ad to show") // Animate fade of banners UIView.beginAnimations(nil, context: nil) // Show iAd iAdBannerView.alpha = 1.0 // Hide AdMob adMobBannerView.alpha = 0.0 UIView.commitAnimations() } func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) { println("iAd failed to load an ad because \(error)") // Animate fade of banners UIView.beginAnimations(nil, context: nil) // Hide iAd iAdBannerView.alpha = 0.0 // Show AdMob adMobBannerView.alpha = 1.0 UIView.commitAnimations() }或者只包含cr / lf 13,10,0组合，你可以在没有特殊程序的情况下输出它。

Answer 2

为了扩展亚当的答案，这可能正是您所寻找的：

carriageReturn BYTE ' ', 13, 10, 0

然后将其称为：

mov edx,OFFSET report1       ;Display sum result
call WriteString
call WriteInt
mov edx,OFFSET carriageReturn ; new line
call WriteString

这样回车就在WriteInt

之后
