Re: a need for speed

Lim,

You could use Query to create the summary.

Order by Area Code, Prefix, Suffix, Terminal.
Break level 1 on Area Code, Prefix, Terminal.
Min & Max on Suffix.
Output to a summary file.

It won't let you output to your own file format.  It will create a break
level indicator field in the output file which you won't want.  You also get
a summary record with min and max on the Suffix over the entire file.  But
it does give you the detail you want.
