Ohhh, come on?!
Are you serious? First you say ...
Every user needs personal database for eComStation (GUI + REXX + Sql)
(?) There was DBExpert and Mesa2
And then you come and tell "something like filemaker" ? Can you define the "something" perhaps more detailed?
You say people need apples or pears and when I ask for details you say they need a fruit shop.
Get back to me when you have a feature list that is realistic and can be put to reality in less than 5 man-years.
