It was '89 IIRC when I licensed the Datatel Colleague product for a college ERP solution, but in a mgmt role. So, it might have been the 90's before I touched it myself.
I gather you mean compared to as an O/S? I have only used Pick in a db environment, first as INFORMATION on Pr1me computers, then UniData on AIX. I've also dabbled with UniVerse on AIX and OpenQM on Linux. None of these call themselves PICK, by the way, and I haven't used any products that have referred to themselves that way.
