The early input scheme for the 4GL supported entry of data within the 72-character limit of the punched card (8 bytes used for sequencing) where a card's tag would identify the type or function. With judicious use of a few cards, the 4GL deck could offer a wide variety of processing and reporting capability whereas the equivalent functionality ...
Informix-4GL is a 4GL programming language developed by Informix during the mid-1980s. [ 1 ] [ 2 ] [ 3 ] At the time of its initial release in 1986, supported platforms included Microsoft Xenix (on IBM PC AT ), DEC Ultrix (running on Microvax II , VAX-11/750 , VAX-11/785 , VAX 8600 ), Altos 2086 , AT&T 3B2 , AT&T 3B5, AT&T 3B20 and AT&T Unix PC .
In the early 1990s, a new PC-based tool for developing LINC specifications was released, the LINC Development Assistant (LDA). LDA was written in a mixture of Smalltalk and C++ rather than the LINC 4GL (the latter of which was not intended to run on a personal computer). From version 17, it was intended that all development be done with LDA.
SheerPower 4GL is a fourth-generation programming language developed by Touch Technologies, Inc. [1] SheerPower 4GL is the result of porting Touch Technologies' Intouch 4GL programming language that runs on OpenVMS (for DEC Alpha and VAX computers) to Windows, launching in 2000. Downloads are free from the official SheerPower 4GL website. [2]
A wide variety of dynamic or scripting languages can be embedded in compiled executable code. Basically, object code for the language's interpreter needs to be linked into the executable. Source code fragments for the embedded language can then be passed to an evaluation function as strings.
Specifications must be subject to a process of refinement (the filling-in of implementation detail) before they can actually be implemented. The result of such a refinement process is an executable algorithm, which is either formulated in a programming language, or in an executable subset of the specification language at hand.
Forté 4GL was created as an integrated solution for developing and managing client/server applications. Forté 4GL consists of an application server, tools for deploying and monitoring an application and an object oriented proprietary programming language, TOOL (transactional object oriented language). Given that TOOL only runs on the Forté ...
[4] [10] Version 1.0 of the WebGL specification was released March 2011. [1] An early application of WebGL was Zygote Body. [11] [12] In November 2012 Autodesk announced that they ported most of their applications to the cloud running on local WebGL clients. These applications included Fusion 360 and AutoCAD 360. [13]
