binary to ascii

[hfheatherfox07]

I was trying to use My own LUT ...that is what I am having a problem with  :(
Donkey wrote a beautiful proc to translate this and it works ,I just want some experience with LUT
I still did not catch why that table that I am trying to use wont work

I think the only place I've ever used a LUT was when converting case, though I doubt its as quick as most other ways of doing it I wanted to try xlatb and have just kept using it ever since...

don't let Hutch see that XLAT instruction   :lol:

LOL, I think he might cut me some slack this one time...

@Donkey
My Problem is the fourth post up from the bottom on the previous page...when I try to add the full LUT table it won't work
The solution that you have previously posted was elegant and fast and that is what I will be using , Thank you again  :t
I just wanted to make an LUT example , Since I never made any thing with an LUT before.

[hfheatherfox07]

@Donkey  is this what you had in mind with your case convert ?
I tried Converting it to masm ... It converts upper case to lower case....
