From my perspective, one of the shortcomings of the way ADDE was cast was the inability to specify a time as LATEST. Since we felt that the concept of LATEST was important/useful, we used the ability of both big and little endian systems to access SYSKEY.TAB to our purpose. Of course, the way we did this was to modify decoders to update SYSKEY.TAB with the information about the time of the most recently received data, what file it was in, and the day for which it was valid. I have not extended this use to the XCD GRID decoder since there is currently no way to access an ADDE server's copy of SYSKEY.TAB remotely (that is to say the copy of SYSKEY.TAB that the remote decoders are updating). I have mulled over a couple of different ways of doing this (an ADDE SYSKEY.TAB server and writing the data currently written to SYSKEY.TAB to a TEXT file that can be accessed remotely by the READ command), but I have not implemented anything yet. Even if such a facility was developed, it would not do exactly what you are asking about. The process of plotting the most recent data would be a two step one: interrogate the server to find out what is LATEST, and then providing that information to the ADDE application that is to be run. If you have any thoughts on this important topic, I would _love_ to hear them! >Thanks, Sorry I couldn't provide better news. Talk to you later... Tom
