Informix-4GL is a

AT&T 3B2, AT&T 3B5, AT&T 3B20 and AT&T Unix PC.[1]

Description

It includes embedded

GUI
(graphical user interface) Generator.

The package includes two versions of compiler which either produce 1) intermediate byte code

Dumb terminals
. A particular feature is the comprehensive error checking which is built into the final executable and the extremely helpful error messages produced by both compilers and executables. It also features embedded modal statements for changing compiler and executable behaviour (e.g. causing the compiler to include memory structures matching database schema structures and elements, or to continue executing in spite of error conditions, which can be trapped later on).

History

The Informix-4GL project was started in 1985, with Chris Maloney as chief architect. Roy Harrington was in charge of the related

DB2 databases. Another flavor of Informix programming-tool was produced, called "NewEra", which supported object-oriented programming
and a level of code-compatibility with Informix-4GL.

Informix was acquired by IBM in April 2001.

UNIX and Red Hat Linux and SUSE Linux
operating systems; the FOURGEN business was later acquired in 2002, by www.gillan.com.
