I'm doing an implementation of a game in assembly in < a href="https://www.labcenter.com/"> Proteus .

I draw two random numbers from 1 to 99 and need to generate an image on the LCD for the numbers I generated.

Example: If I generate number 1 the image that will appear in the display is

IfIgeneratenumber2theimagethatwillappearinthedisplayis

Implementation was done as follows: 

.DATA    
SEED DW 0 ;Armazena o número aleatório de 1 ~ 99
NUMBER1 DW 0 ;Guarda o primeiro número gerado  
NUMBER2 DW 0 ;Guarda o segundo número gerado

IMG_NUMBER1 DW ? ;variavel aux para armazenar a IMG do primeiro numero gerado
IMG_NUMBER2 DW ? ;variavel aux para armazenar a IMG do segundo numero gerado

..... IMG_NUMERO_3, IMG_NUMERO_4 ... até 99

In the code I wrote like this to generate the random number and save in the auxiliary variables for comparison at the end of the game: 

CALL RANDOM
MOV NUMBER1, SEED ;Guarda o primeiro numero gerado
CALL RANDOM
MOV NUMBER2, SEED ;Guarda o segundo numero gerado

I have NUMBER1 and NUMBER2 the values of random numbers generated.

I made the following way to search the generated number and store the memory position of the image referring to the number: (Stores in BL before calling COMPARE_NMB , value 0 to fetch the image of NUMBER1 and 1 for NUMBER2 ; In AX it contains the value of NUMBER *) 

COMPARE_NMB:
   PUSHF
   PUSH BX
   PUSH AX
   PUSH CX

   CMP AX, 1
   JE JE_1 ;PULA PRO METODO SE FOR 1   
   CMP AX, 2
   JE JE_2 ;PULA PRO METODO SE FOR 2
   CMP AX, 3
   JE JE_3
   ... assim por diante até 99 ...

For each J E what I call it: 

JE_1:
    LEA SI, IMG_NUMERO_1
JMP CONTINUE
JE_2:
    LEA SI, IMG_NUMERO_2
JMP CONTINUE
....

CONTINUE:
   CMP BL, 0 ;VERIFICAR AONDE ARMAZENAR
   JE ARMAZENAR_IMG1
   JNE ARMAZENAR_IMG2 
...
ARMAZENAR_IMG1:
    MOV IMG_NUMBER1, SI
JMP FINALIZAR
ARMAZENAR_IMG2:
    MOV IMG_NUMBER2, SI
JMP FINALIZAR

But I do not think it's the best solution.

Would anyone know a more practical method?

Create a new variable and store it as an array of memory locations , if I want to image1 I would only do posicoesImagens[NUMBER1] , or image2 , posicoesImagens[NUMBER2] , something like this.

Note: Yes, I currently generated 99 variables to store each image for each number. My editor is still struggling with the amount of information in the code.

I wrote 500 lines just to compare what the number is generated. And I had to write 2178 lines relating to the images of each number.

DS stands for Data Segment.

A possible solution would be to write the code in C and ask the compiler to generate the assembly for you. 

gcc -Wall -c programa.c
