.model small

Mode small supports one data segment and one code segment. All data and code are near by default. stack 100h

stack 100h reserves 100h bytes for stack msg1 db 0DH,0AH,"Enter any base from 2 to 35 ","$"

Here enter the base value from 2 to 35 which will stores in $.

num2 dd?

num2 dd means define double word for num2

num1 dd?

num1 dd means define double word for num1

count db 0 considercount db is o num3 dd 10 num 3 define double word for 10 main proc main procedure of a code mov ax,@data copy @data to ax mov ds,ax copy ax to ds mov dx,offset msg1 copy offset msg1 to dx jnz loop1 jnz loop1 sends the program back to loop1 moveax,num1 dec num2 num2 value is decremented sub al, 30h 30h is seperated from al.

Take your time,,,, no rush... thanks
