A more flexible approach:
[Bx+si] and [Bx+di]
Offset address: (BX) + (SI)
mov Ax,[bx+si] = mov Ax,[bx][si]
(AX) = ((DS) *16+ (BX) + (SI))
[Bx+si+idata] and [Bx+di+idata]
Double loop:

When you use this notation, we will find that the console error error:invalid value for attribute cx= ' {{cx}} '. This is due to the limitations of the SVG DOM API, which you cannot simply write as cx= "{{
In order to prevent the virus from attacking the hard drive or other misoperation, it is an effective way to backup the hard disk boot record. If you do not have off-the-shelf tool software (such as srctools, a very useful tool, can be downloaded in the "Disk Utility", its specific use of the site "DOS article" column introduced its article), can be implemented with Debug. The method of backup and write the master boot record of the hard disk is introduced.

. Keep the form on top
Sometimes an application needs a message or the total of the query window to remain at the top, that is, using reading to switch to other forms, you can see the form, such as the Find form in Microsoft Word, which is implemented by calling Windows API function SetWindowPos (), as shown in the following example:

An example of an AVI file containing true color images is given, in which the cavicreate () function is used to read AVI file information and initialize members of Cavi class, for example, to define the width, height and cavi of each frame image according to AVI file information. The information header structure of each frame image and so on; function aviread (int mframe) is used to read the Mframe frame from an AVI file. The implementation code appears as follows:
