Assembly Language Learning 3 assembly write EXE

1. The assembly language source program has two kinds of instructions, a assembly instruction, a pseudo-directive.
2. The assembly instruction has the corresponding machine instruction, finally executes for the CPU
3. The pseudo-directive does not have a corresponding machine instruction, which is executed by the compiler.
4.assume,segment,ends,end all pseudo-directives

First step: Write the Assembly source code

New text 1.txt

The code is as follows:

Assume CS:CODESG; Associate CS Register and CODESG code snippet

CODESG segment; CODESG Code snippet Start

MOV ax,0123h
MOV bx,0456h
Add AX,BX
Add Ax,ax

MOV ax,4c00h
int, mov ax,4c00 int 21 These 2 instructions implement program return

CODESG ends; CODESG Code snippet end Segment,ends paired use

End; complete assembler.

Step two: Compile the connection to the source code

Download the MASM5 compilation tool and put it in the C packing directory

Step three: Get the final exe
