Re: Tool to diff (compare) database table data
Off hand, do you know if Comparex is mainframe only? It's not immediately clear from reading the Datasheet.

All the words I see on the datasheet speak mainframe to me.
A dusty brain cell tells me I first encountered Comparex in the
early 1970s. So it's O-L-D.
What I remember is that it had a huge list of features &
capabilities. It had the kitchen sink & then some.

There's an old joke... "Old hardware goes to the junk pile. Old
software goes into production."
In 1996 Capers Jones (Mr Function Points) sent me a list of the 440
languages he was monitoring. By 2005 the list had expanded to 600,
but was then pruned back to 500.
Cheaper, more powerful hardware with HUGE disks plus smart people
equals more & more languages.
