Dyalog TTY IDE

The original interface to Dyalog – a UNIX (or VT-100) style terminal session, with a fixed-size screen full of characters. The default interface for Linux. An interactive APL REPL, editor, debugging tool.

We will continue to provide this interface for use in situations where no GUI is available or where developers prefer the retro look!
