The rules I gave, originally are the rules I follow.

>So in rules 1 and 2, when you use the word 'Never', you didn't really mean Never, did you?

>Oh, wait, I think you just inadvertently omitted a few words:
>
>Never use alltrim() in an index expression ............ without using Padr to insure you end up with keys of the same length.
>
>
>>Yes and no; that's in fact rule no. 4: If you absolutely need to use alltrim() since there are no other options, you must use padr() to make sure that you end up with keys with the same length.
>>
>>>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!!!
