Well like (ex):

If XXXX
    SCAN
      If YYYYY
         Do while ZZZZ
           If AAAAA
               Line of code 10
           EndIf
         EndDo
      Else
          Line of code 1
          Line of code 2
          Line of code 3
          Line of code 4
      EndIf
    EndSCAN
Else
    Line of code 5
    Line of code 6
    Line of code 7
    Line of code 8
    Line of code 9
Endif

Then it's a lot easier to understand, rather than all over the place as you presented it, where first one has to sort out the indentation and follow the logic before one can decypher and understand the code

>T.
>how do you do it.
>>M.
>>
>>I wouldn't even attempt to follow the logic in the crazy indentation you've provided.
