All rules have exceptions:

Using Padr() on the whole group of AllTrims (or any other Trim) gives you keys of all the same length.


>Rule no. 1: Never use alltrim() in an index expression
>Rule no. 2: Never, NEVER, NEVER use alltrim() in an index expression
>Rule no. 3: If you need to use alltrim() in an index expression, see rule no. 1 and 2.

>NB! In case I forgot to mention it: Never use alltrim() in an index expression!!!
