Thank you for your responses - they are much appreciated. I agree with everything you say, but as usual there are exceptions from time to time. i.e. remember the ol' dB... this and dB... that because "dBase II/dBase III/dBase III+" was part of a trademark/accepted reference (whatever you want to label it) - well in our case "dM" is in the same classification or "doubleM" as the name of the company starts with doubleM.
I'm showing my age by knowing the "dB" reference - but it's true, it's true
Again, thank you for your responses...
