indeed there is not much difference with the previous post just replace the repeating character by repeating a sentence but there is one thing that can cause a striking error when combined words, and on this occasion I will give a little tutorial how to repeat the sentence in programming assembly and you should follow the steps below:

First you have to install the Emulator8086 application you can dowload Here, Because besides the capacity is not heavy and easy to use.
Then, before I start writing syntax I will show the ASCII code that I had a previous language and codenya is divided into two parts namely in binary code printing and printing regular numbers and usually simple programming using only binary code as the training and ASCII code as below:

ASCII Code in numbers

ASCII Code In Biner

Then you should type the following syntax for the occurrence of repetition of letters in programming machine and the syntax will be described in detail

In the syntax below it is explained that printing macro characters can be explained in the syntax MOV AH, 02 which MOV brings the AH variable to the binner number 02 and for MOV DL,Kar bring the DL variable into a character as a macro printe

Cetak_Kar MACRO Kar 
LOCAL Ulang             
    MOV AH,02 
    MOV DL,Kar

In the syntax below can be explained that the integer used is 21H which means using binner number in macro character printing and also pengakirhan MOV syntax declaration

Ulang:                
    INT 21h         
    ENDM

This directive mark is used to tell the assembler the form of memory used by our program and In the COM program this command will always be used. This command is used to notify the assembler so that the program at run time (loaded into memory) is put starting at offset to 100h (256) bytes.

 .MODEL SMALL 
.CODE 
ORG 100h

On this syntax brings the BL variable to 05

    MOV BL, 05

At this stage is the formation of macro characters that will be printed with a call letter that is inputted in Cetak_Kar so that the macro program can be executed

Ulang2:
Proses:
Cetak_Kar 'R'
Cetak_Kar 'I'
Cetak_Kar 'C'
Cetak_Kar 'K'
Cetak_Kar 'Y'
Cetak_Kar 20h

In this syntax serves as a closed ASCII code declaration that makes macros characters

    INT 21h
    DEC BL
    JNZ Ulang2
    END Proses

All Syntax Here

Cetak_Kar MACRO Kar 
LOCAL Ulang             
    MOV AH,02 
    MOV DL,Kar
     
Ulang:                
    INT 21h         
    ENDM            

.MODEL SMALL 
.CODE 
ORG 100h
    MOV BL, 05
Ulang2: 
Proses:
    Cetak_Kar 'R'    
    Cetak_Kar 'I'   
    Cetak_Kar 'C'   
    Cetak_Kar 'K'   
    Cetak_Kar 'Y'
    Cetak_Kar 20h
    INT 21h
    DEC BL
    JNZ Ulang2 
END Proses
