Write an 8086 assembly language program to compare the two string of the same length

Hopefully you have a tab on the memory card. If you do, just move the tab to allow writing to the card. Can you copy memory to another memory card for ps2? Simple answer is yes:

Write an 8086 assembly language program to compare the two string of the same length

The following information is provided courtesy of Kenneth G. LF95 Conventions This section is intended to assist the experienced assembly language programmer in writing subprograms that can be called by LFcompiled Fortran code.

In addition to this information, you should also have on hand appropriate documentation for your assembler. Each sample program can be compiled and linked by using the GEN.

Write a ALP that copies a string to another location in the memory A floating point number consists of a fraction binary or decimal and an exponent bianry or decimal. Both the fraction and the exponent each have a sign positive or negative.
Avoid instructions outside any segment Data Registers Four bit data registers are used for arithmetic, logical, and other operations.
Assembly Language We have already used variable length strings in our previous examples. The variable length strings can have as many characters as required.
The OR Instruction Write your program and if you are having a problem post it here with a description of the problem you are having.
Assembly Language Statements In this document, we study assembly language, the system for expressing the individual instructions that a computer should perform.

BAT file that accompanies it. If any of these registers are used in an assembly-language routine, they can be saved by pushing them upon entry, and then popping them before returning. Argument Passing LF95 passes numeric and logical arguments by pushing their addresses onto the stack, from right to left.

The ESP register itself contains the address that control will return to in the calling routine, upon subprogram termination. The arguments can then be accessed using EBP instead of ESP, and any additional pushing or popping will not result in any confusion about where the argument addresses are.

These length parameters are treated as though they were to the right of the actual parameters in the call, and so they are actually pushed first, and are at higher offsets relative to EBP. Passing Arguments to Subroutines It is often easiest to learn a programming method by studying examples, and so we will now show and examine several cases in which a Fortran program calls an assembly language subprogram.

Since the EBX register is used in the processing, its contents must be preserved by being pushed onto the stack before it is clobbered, and popped off later.

LF95 assumes that the caller will fix the stack, i. As a result, the return to the calling routine is accomplished by means of a simple RET instruction. Now, let us examine a case in which a subroutine contains some local data. This is the Fortran part: Quantities stored in this manner could be changed during the course of computation, if required.

Alternatively, this routine could have been written with the constants 7 and 3 being coded as immediate data in the MOV and ADD instructions that use them. Floating point arithmetic is also possible in an assembly language routine that is called from an LF95 program. If it is necessary for an assembly language subroutine to access the contents of a COMMON block, then we must find the starting address of that block.

The two arguments are not, however, pushed consecutively onto the stack.

String Instructions

In this code, we do not make use of the length of the second string, assuming it to be equal to that of the first one. Since we use the ESI and EDI registers in this subroutine, we save their previous values on the stack and restore them before returning.

The only difference in the calling sequence is that a FUNCTION returns a value, and the method that is used to send the result back to the calling routine depends upon the data type of that value.Mar 11,  · Program in ASSEMBLY to Compare two strings (MASM );=====Macro for caluclate length of string===== LEN MACRO str mov di,offset str mov bl,0 L: cmp [di],'$ Program in Assembly Language to check if number is Prime b\w (0 - 9) $" AHSAN1 DB 0DH,0AH,"IT IS PRIME NUM Soft drink machine simulation code in C++.

Learn Assembly Language. Why do we need to calculate the length of a string? Well sys_write requires that we pass it a pointer to the string we want to output in memory and the length in bytes we want to print out.

If we were to modify our message string we would have to update the length in bytes that we pass to sys_write as well. This program can be done in the same approach as question read string mov dx.
