A fourth-generation programming language (4GL) is a high-level computer programming language that belongs to a class of languages envisioned as an advancement upon third-generation programming languages (3GL).
The key to CorVision is PROCEDURES. The procedures in CorVision eventually become Executable Images (.EDO's). Three types of procedures are: Screen Procedures Used for data entry and updating, can be accessed from a menu and is navigatable.

Basic4GL (B4GL; from Basic for openGL) is an interpreted, open source version of the BASIC programming language which features support for 3D computer graphics using OpenGL. While being interpreted, it is also able to compile programs on top of the virtual machine to produce standalone executable programs.
Where LINC (and LIRC) specifications had previously been held in source-code files, they were now held in a database (designed and developed using the LINC 4GL) and subject to rigorous automatic validation. The new LINC-based system in which specifications were stored was named LINC interactive or LINC Development Environment (LDE).
A 4GL will eventually generate some type of 3GL code, which is compiled and executed, but you never need to modify the generated 3GL. It should not matter which 3GL is used. A High-Level Application Definition should allow you to generate or regenerate the same applications in different languages to make your applications portable.
Uniface is a low-code development & deployment platform based on a proprietary procedural scripting (fourth generation) language called Uniface Proc that is used to code application behavior. Uniface automates most input/output operations through its kernel and default code, so much fundamental behavior does not need to be coded.
RAMIS ("Random Access Management Information System") is a fourth-generation programming language (4GL) capable of creating and maintaining databases consisting of named files containing both numeric and alphabetic fields and subsequently producing detailed simple or complex reports using a very simple English like language.
