Assembly Variables, how to manage 'em ?

[gunaR]

Hi!
I'm a assembly begginer and i have a question.
I know how to retrive a Keyboard Input to a RECORDER(AL)
but i dont know how to put AL into a not-initialized variable(VARIABLE DB ?).
So, how to do it ?
2. How to add a caracter to a variable without modifying the start of it ?
Thanks a lot,
long life to asm!
