Ace and Perform was part of a product called Informix 3.30 from RDS. Informix 3.30 made direct access to database files and included: - Ace report generator (this is the reason because ace compiler command of informix sql is called sace). QUEL based. - Perform screen generator - Informer query language, QUEL based. - Enter1 and Enter2 screen generator to direct entry to tables. - A menu program that comes witj sources called dbmenu (then sysmenus in isql and source closed). - DBBUILD data description language to describe and change database tables (this was very good because we described it and a command made the syncronizations. Much better then hand made alter tables). - ALL2 library to access to the database with C S'rgio >Jonathan, I think you make a lot of sense with your version of things. >One thing I can confirm is that Turbo was launched in 1987, after all >that was why I joined the company, and I4GL was about 1 year before >that.
