Action! Programming Language

Action! is a programming language for the Atari 8-bit family of microcomputers. It features an integrated editor, a debugger, and a 6502 compiler. Action! was created by Clinton Parker and released on cartridge by Optimized Systems Software (OSS) in 1983. Its syntax is similar to that of ALGOL 68. Action! is significant for its high performance, which allows games and graphics demos to be written in a high-level language without the use of hand-written assembly language code. Action! language constructs were designed to map cleanly to 6502 opcodes. In 2015, Clinton Parker released the Action! 3.6 source code to the public under the terms of GPL. This project is intended to preserve the Action! source code, provide fixes for known bugs, and add new features in version 3.7. Join us at AtariAge https://forums.atariage.com/topic/217770-action-source-code for questions and discussions. Check out https://atariwiki.org/wiki/Wiki.jsp?page=Action for related information.

CalcuFp

New version: CalcuFP program is a calculator software (beta version), has a wide range of mathematical functions, specific functions for different subjects (ex.- IPv4 functions), Apart from being able to have on hand an wide range of functions, allows to use different numbering systems WITHOUT CHANGING MODES. We can sum operations decimal, binary and hexadecimal mixed. Example. - 25 + BIN ('111 ') + HEX (' FF ') -> this is equivalent to adding the integer 25 +7 (binary) +255 (hexadecimal) = 287. Allows use of predefined variables and constants. Creating user functions. It has a programming section through type pascal scripts (still in testing), It has a multimedia viewer to store documentation that we have on hand for our daily tasks. Aside calculators comes with color coded for resistors, inductors and capacitors. Support matrix calculation. Solving systems of n equations. Periodic table of elements. QR code generator Create new User functions with pascal script.

REXX

REXX is a programming language originally developed by IBM and over time included in all IBM operating systems (e.g. OS/2, AIX and PC DOS). In addition to this, various IBM and non-IBM implementations have been made available for most operating systems/environments (including free implementations for Win32/Win64, Linux, Mac OS X, Solaris and many others - e.g. Regina, Open Object Rexx). This interface unit makes it possible to inter-mix code written in Pascal with REXX.

EDITEL

One of the hardest things to do when coding with COBOL is translating a screen design into code. The process may take hours, not to say days. In my old BLIS-COBOL, COBOL 74 and COBOL 80 /85 days (and those last 2 had the SCREEN SECTION which helped a lot !), I recall spending a significant amount of time dedicated to that activity. Time that could be used for more productive activities like coding and resolving bugs, for instance. Having said that, I developed a Screen Editor (similar to a Screen Painter, as some tools may call it) which allows the user to create screen layouts (which includes the use of colors) with delimited fields and respective input masks, and finally generate the SCREEN SECTION code that reflects that layout. All of it automatically - no code needed. The idea came from a program I used to use named EDITEL. I have adapted the concept (it was originally built for BLIS COBOL systems) and created a version that does this for GnuCOBOL and Microfocus COBOL. Enjoy !

Tron

Tron is a console application (now discontinued) which simulates user intervention for otherwise unscriptable applications. It can simulate keystrokes, mouse clicks and movements from scripts allowing the control of applications running in the foreground. It can be used to write automated tests for user interfaces or to ease repetitive jobs with applications which do not support scripting natively. It has a modular design which allows it to be extended easily and is not tied to any particular scripting or programming language.
