Hi David, I believe I have what your looking for, or at least something that may meet your needs. I wrote such a GX awhile ago.
Here's how it works so you can determine if it meets your needs. - You have an existing database containing Lines, 1, 2, 3, 4, 5, etc which I believe the GX refers to this as the master database - LINEMERGE.GX places the lines in another database. I believe I refer to this as the line database. - The line database will contain one really long line. The long line will contain Lines 1, 2, 3, 4, ... indexed according to a channel in the master database. E.g. if you create a date channel in the masterdatabase, you can use this as the index channel. -The GX creates a channel called LSEP. This tells you where the lines begin and end. It's basically just a binary on-off channel. During the line, LSEP=0. One fid separates the lines and for this one separator fid, LSEP=1000. - As the way I designed it, you can only copy up to three channels from the master database to the line database, but you should be able to modify the GX to handle more. I wrote this GX because I wanted to concatinate all the lines, display the profile, in order to see how the signal that I was measuring behaved over the course of the day.
