Abstract: This article
Program And. when the EXE program is loaded, different memory images are obtained :. the com program has only one physical segment. The maximum length of the segment is 64kb :. the com program can only start at 100h of the Offset address. DOS pair. the length of the EXE file is not limited, so it is easy to organize large applications; and. in the EXE file, end start labels are used to describe the start point, push ds is used to save the

1. The processor may be in the following states before an exception occurs:
1.Handler
2.Thread, MSP
3.Thread, PSP
Ii. Exceptions:
1,There is a stack pressure process. If PSP is used when an exception occurs, it is pushed to PSP. If an exception occurs, it is pushed to MSP.
2,The LR value will be set based on the processor mode and the stack used (of course, the

Otherwise, MS-DOS allocates as much memory as possible (until all memory is reserved), even if. The COM program itself cannot be larger than 64K. Most of the before attempting to run another program or allocate additional memory. T

A com file is a memory image file of an executable program. It is similar to the executable program structure in the CP/M operating system of an 8-bit machine with only 16-bit address lines. During the execution of the COM program, besides the DOS and rom bios functions, and the user's specific arrangement, the segment register is generally not changed. The four segment registers share the same content and all point to

program (TSR. In C, you can use the keep () function to resident the program in the memory. This function has two parameters: Status and size. Size is the length of the resident memory, which can be obtained using size = _ SS + _ sp/16-_ PSP. Of course, this is also an estimation method, not an exact value. After the function is executed, the exit status information is saved in status. For example, for the above example, rewrite "geninterrupt (0x60);
0x60 interruption */} experienced readers can easily get the execution result of the program: the screen displays "This Is An examp Le !". This section describes how to compile and install an interrupted service program. Next, let's talk about writing and using a memory resident program (TSR. In C, you can use the keep () function to resident the program in the memory. This function has two parameters: Status and size.
