9、operation stepsDebugger DEBUG:DEBUG.EXE debugger is a debugging assembly language program provided by DOS, each version of the DOS with the program, with tracking program operation, setting breakpoints, modify the memory and display the contents of the registers and other functions, can also be comp

10、iled debugging for the short program.Dynamic debugger DEBUG.COMIn the process of compiling and running an assembly program, there will be some mistakes and problems. It is necessary to analyze and debug the program. The debugger DEBUG is a debugging tool specially designed for assembly language. It

11、has a strong function in debugging assembly language program, can make the programmer access to the inside of the machine, can observe and modify register and storage unit, and can monitor the implementation of the target program, users really come into contact with CPU, have the most close working

12、relationship with the computer.Implementation of DEBUGDEBUG command formatPrimary DEBUG commandImplementation of DEBUGIn the operating system (DOS or WIndows) command line, directly into the DEBUG program, type the command in the following format:DDEBUG d:Pathfilename.extParm1Parm2The content is opt

13、ional ,Yes, we can. We can also default.d: drive number, to call into the DEBUG state of the executable file in which the driver, such as A:, B:, C: etc.Path is the path to the executable file in the DEBUG state in which directory or subdirectory.filename.ext, being transferred under the condition o

14、f DEBUG executable file, the file can be edited, compiled by, after connecting the resulting executable program can also be section of assembly in the DEBUG state, the write command W written to disk file.Parm1Parm2 is an optional parameter, which is the specification parameter for a given file.When

15、 you start DEBUG, if the filename (file name) is entered, the DEBUG program loads the specified file into memory, and the user can modify, display, or execute the specified file through the command of DEBUG. If you do not have a file name, you work with the contents of the current memory, or load th

16、e required files into memory with either a naming command or a load command, and then modify, display, or execute by the DEBUG command.When the DEBUG program is started, a - appears on the screen, indicating that the system has entered the DEBUG state.DEBUG command format(1) the DEBUG command is an

17、English letter followed by one or more arguments. Multiple operating parameters are separated by , , or space.(2) the DEBUG command must then press the ENTER key, and the command is valid.(3) parameter, whether it is address or data, are expressed by sixteen hexadecimal number, but sixteen decimal d

18、ata do not use H.(4) you can use Ctrl and Break keys to stop the execution of a command and return to the prompt at DEBUG.(5) with CtrlNum Lock key to abort the output line is up, then continue to output information and press any key.Primary DEBUG command(1) assembly command AFormat: a. A section re

19、gister name: offset addressB. A segment address: offset addressC. A offset addressD. AFunction: the assembly language program can be directly assembled into memory by this command.When you type the A command, display segment address and the offset address waits for the user to enter the assembly ins

20、tructions of each type in a carriage assembly instruction, automatically display the address of the next instruction and offset address, and then type a instructions, until all typed assembly language program, and can directly display the next address type return back to the prompt -.Where the segme

21、nt address of the A is in the segment address register, therefore, when the command is used, the segment address register must be sent to the segment address, the address of the C is in the CS, the segment address of the D is in the CS, and the offset address is 100H.(2) display memory command DForm

22、at: a. D addressB. D address rangeC. DFunction: displays the contents of the specified memory range.The content is displayed in two forms: one is the sixteen decimal content, the other is the ASCII code character corresponding to the sixteen division, and the invisible character is replaced by .For

23、a and C, 128 bytes of content are displayed each time, and the number of bytes shown by the B is determined by the address range.If there is an address in the command, the content displayed starts at the specified address, and if no address in the middle (such as C) starts from the next cell of the

24、last cell shown in the previous D command. If we have not used the D command before, the content of the segment register initialized with DEBUG is the start segment address, and the initial offset address is 100H, or CS:100.For a, the address is an offset address, and the segment address is CS. For

25、the address range in B, you can specify the segment address and the initial offset address and the termination offset address.(3) modify the storage unit content command EFormat: a E address content tableB E addressFunction: a replaces the memory cell content of the specified address range with the

26、given content table of the command.B - modify unit content one unit at a time.Where: the content table is a sixteen hexadecimal number, or a string of characters enclosed in single quotes.(4) fill memory command FFormat: F range unit table of contentsFunction: repeat the contents of the unit content

27、 table into the specified range of memory.(5) memory move command MFormat: M source address range target starting addressThe source address range and destination start address are the offset addresses, and the segment address is DS.Function: moves the contents of the source address range to the stor

28、age unit starting at the destination start address.(6) compare command CFormat: C source address range target addressWherein, the source address range is a contiguous memory unit pointed out by the start address and the termination address, and the target address is the target address starting addre

29、ss in comparison with the source address pointing unit.Function: from the source address range, starting from the starting address unit, sequentially comparing the content of each cell with the target start address, then comparing to the source termination address. The comparison results if the agre

30、ement does not display any information, if not, the failure unit address and contents are shown in to the content source source address destination address in the form of content. .(7) search for the specified content command SFormat: S address range tableFunction: search the contents of the table w

31、ithin the specified address range and search to display the address of the elements in the table.(8) check and modify register contents command RFormat: A & RB R register nameFunction: a shows the contents of all registers in CPU and the status of all flag bits.B displays and modifies the status of

32、a specified address setter and its flag bit.Wherein, the status flag register FLAG is displayed as a bit, and when displayed, the display order and symbols of the 8 status flags are shown in table B - 1.Table B - 1 status flag display formFlag bitStatusDisplay form (set / reset)Overflow flag OFHave

34、sB T= address number or T address numberFunction: a executes instructions at a specified address, stops, displays the contents of all registers in CPU, and the status of all flag bits, as well as the address and content of the next instruction.B is a plurality of tracking commands, starting at the s

35、pecified address; if ordered by address given the starting address, from the starting address, if not given, from the current address (CS:IP) to execute the command in the number a total of a few instructions after tracking decided to return to DEBUG.(10) disassembly command UFormat: a U addressB U

36、address rangeFunction: the code within the specified range is displayed in assembly language, and the address and machine of that code are located in memory.If no address is specified in the command, the next element of the last instruction address of the above U command is used as the starting addr

37、ess;If the U command is not entered, the value of the DEBUG initialization segment register is used as the segment address, and the 0100H is used as the offset address.(11) named command NFormat: N file nameFunction: in the call to DEBUG, no file name, you need to use the N command to call the name

38、of the file format to the file control block CS:5CH, can use the L command to put it into memory debugging (other reference manual DOS).(12) read disk command LFormat: number of sectors read a L starting address driver No. sectornumber.B L addressC - LFunction: a read the specified drive and specifi

39、ed sector range into the specified area of memory. Where the address is the start address of the read memory, and when the input does not have a given address, the implied address is CS:100H. The initial fan area refers to the starting position of the logical fan code. The number of sectors read ref

40、ers to the contents of several sectors of memory beginning with the initial fan code. Driver number is 0 or 1, 0 a, 1 B disk.B read the file specified by the file control block that has been formatted in CS:5CH. Before using this command, you can format the filename you want to read into the file co

41、ntrol block of CS:5CH, where the address is the memory address, by naming the N command.C and B addresses are implicit in CS:100H.When the file read has an extension,.COM or.EXE, it is always loaded into the CS:100H, and the address specified in the command is useless.Where the bytes of the read fil

42、e are stored in BX and CX.(13) write the disk command WFormat: A, W, driver, starting address No. sectornumber, written by a number of sectors.B / WaddressC - WFunction: a. Write the program or data in the DEBUGU state to the specified drive, start the area code, and write the number of sectors to m

43、ake up a few sectors of the disk.Write the specified sectors of the operation should be very careful, if the error will destroy the original contents of the disk.If the address in the command line contains only offset addresses, the W command holds the segment address in CS.B - when typing the write

44、 disk command without arguments, or typing only the write command of the address parameter, the write command writes the file to the floppy disk. The file is formatted with the naming command N in the CS:5CH file control block before using the W command.When C only has no arguments before the W comm

45、and, the N is used in conjunction with the write disk operation.The number of bytes to write to the file in BX and CX before using the W command.(15) output command OFormat: Oport address byte valueFunction: outputs a byte to the specified port address.(16) run command GFormat: G = address address.

46、Function: execute the program that the user is debugging.The address is the start address of the execution, and the content in the CS is the section address, and the address at the back of the equals sign is the offset address. The address at the back is the breakpoint address. In the command line,

47、there is only the starting address and no breakpoint address, and the program is not interrupted at execution time. DEBUG specifies the maximum set of 10 breakpoint addresses. Setting breakpoints for debugging large programs, namely programs have multiple modules, multiple paths are used, more conve

48、nient, no matter where in the execution path, the program can be stopped at the breakpoint, so as to adjust the program.The breakpoint address is the offset address at the program interrupt, and the segment address is in the CS.When you execute a small program that is compiled in the DEBUG state, us

49、e only the G command.(17) sixteen decimal operation command HFormat: H data 1 data 2Data 1 and data 2 are sixteen hexadecimal data.Function: add and reduce the two sixteen decimal numbers,The results are displayed on the screen.(18) end DEBUG and return to the DOS command QFormat: QFunction: the pro

50、gram is debugged, quit DEBUG state and return to DOS state.The Q command does not save memory files. If you want to save it, you must write the disk with the W command before exiting DEBUG.Three, experimental content:1. reference materials, familiar with the use of DEBUG2. master the basic commands
