DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.

sorry about that

You need to check if the last output character was Z, and if so, rewrite that instead of the underscores.

Member 10548351 25-Jan-14 4:54am

those underscores are suppose to be spaces, i tried putting spaces but when i checked preview it aligned it vertically
anyway i want to fill those spaces with the corresponding letters
just not sure what to do or how to do it

ok, but can you show me it to me using the method im using? the one with mov, rcx, loop, dlbl

Just follow what I have written below and convert it into actual assembler instructions. It's a good exercise for you.

You need to think about this in logical terms, rather than in assembler terms. Each letter should be repeated according to its position in the alphabet. So the program should be something like:

Set letter := 'A'
Set count := 1
Loop:
    Set repeat := 0
    Print:
        Display letter
        Set repeat := repeat + 1
        If repeat .LT. count Goto Print
    Display NEWLINE and RETURN
    If letter .EQ. 'Z' Goto Exit
    Set letter := letter + 1
    Set count := count + 1
    Goto Loop
Exit:
