1.2 Safe to install
Innovative Utility Tool for Creative Professionals

j901 by Ian Clark offers a sleek and intuitive interface that enhances productivity for artists and designers, making complex tasks simple and efficient.
J is a general-purpose programming language that draws inspiration from APL, both stemming from the innovative mind of Ken Iverson. J excels in mathematical, statistical, and logical analysis of text and numerical data.
J901 serves as the successor to J701. This iteration of the J Integrated Development Environment (J IDE) leverages version 9.3 of the J Engine.
- Discards a special keyboard in favor of utilizing custom keys on the system keyboard
- Session log display options include showcasing the whole log or specific parts like inputs-only or transactions containing a designated J primitive or substring
- A comprehensive code editor featuring tabs and a search function
- Introduction of a shell-type preprocessor for common maintenance tasks on jscripts and various files
- Dedicated scenes for showcasing output from functions such as "plot" and "viewmat"
- Context-sensitive Help along with NuVoc lookup capabilities
- Integration of the new "Mill" feature providing insights into noun transformations, e.g., numeric arrays and animated character graphics like Conway's Game Of Life
Aligned with other J IDEs, this iOS application is freely accessible to aid educators and students in mathematics, statistics, science, and engineering. It also caters to J experts who typically rely on desktop setups for professional endeavors. Optimized for iPads but functional on iPhones, it primarily serves as a tool for exploration and enjoyment.
DO NOT USE FOR MISSION-CRITICAL WORK – iOS end-user security trumps app recovery.
