David The Command object does have a Response property which is like the THIS in your example. But that would have to be logged in some way. Also, if you're running UniVerse, it may create an entry in the errlog ..

This caused a 'Exec' of a "SELECT" to fail, but here's the kicker -- in BASIC, we could have 'seen' the error with CAPTURING and RETURNING -- but I'm told the interface to UniObjects does not return this diagnostic information on the 'Exec'... So in BASIC, I would have EXECUTE 'SELECT FILENAME WITH DICTITEM = "A"' CAPTURING THIS RETURNING THAT And I could 'query' what is in THIS and THAT to decide if there is a problem if the "DICTITEM" didn't exist for some reason. I'm told that the product we're using cannot do this same thing -- there is no way to 'know' the message 'select criteria DICTITEM is not a field' was returned from the 'Exec' as we could have seen in the BASIC EXECUTE. Is there no way to get back this same REALLY valuable feedback in UniObjects? How do you code for this issue in UO? This would not be big deal if we had source code or a 'log' of what was happening -- we just had a screen that didn't come up, and with dozens of fields, it's not obvious what the issue was -- until we found it! But the failure of the 'SELECT' command causes the 4GL based on UO to just 'die' I don't want to be stung another time with this, and am never afraid to ask for thoughts or ideas!! If there is a way to handle this, I want to find it and get the idea into their head so I never have a 'lost day' trying to hunt down this kind of issue... TIA!!
