In this module we have worked on character, string and number printing to display . There is register called AH in the INT. If AH= 1, it means the input and if AH=2 ,it mans the output. Actually ASCI code is such a value how the computer understands what value is giving to the computer. AH= 2.it means the output instruction. And it always pointed in the 'dl' register.
If we want to type single word by an output then we will type a '$' after the word. Suppose we want to type 'TURKY' . We will write , A db 'TURKY$' .When it will show as output then then the sign $ will not be shown. For string we will take AH=9 . The output of string will stay in register DX. And a function called 'LEA' means load effective address will be used to get the string as output.
If we want to get any character as output then we will take DX=97h .
