Yap i got his idea, but was having problem implementing that.
So he store the all vowels in a string, then compare the vowels with a given string.
but I was having problem of putting
str1 db "aeiouAEIOU", 0 into the way you coded,
and i don't really get whats [edx+edi] does.
Btw thanks for a very nice commented code, it helps a lot
