RETRO-EXTEND(1) General Commands Manual RETRO-EXTEND(1) RETRO-EXTEND retro-extend - a modern, pragmatic forth development system SYNOPSIS retro-extend image filename [filenames] DESCRIPTION RETRO is a modern, pragmatic Forth drawing influences from many sources. It's clean, elegant, tiny, and easy to grasp and adapt to various uses. retro-extend is a tool to load additional code into an image file. It takes the name of an image file and one or more source files to load into the image. After completion the image file will be updated with the changes. CAVETS retro-extend only emulates the minimal console output device. If the source files require additional I/O to be present, the extend process will likely fail to work correctly.
