>Michelle, if you're getting an error that it can't find a variable "tname", then I suspect you're using a literal for the index name instead of passing it as a character string--or vice versa. You don't give the code that generates the error, so as an example:
>
>LOCAL tname
>tname = 'byID'
>SET ORDER TO (tname)
>
>is different from
>
>SET ORDER TO tname && where tname is literally the name of the index.

The second example is what I'm doing.

Thanks,
