flat assembler

This section contains programs created with the flat assembler and contributed by users as sample material for others to learn from. Most of them were submitted in the early days of this website, and they all have been designed for flat assembler 1.

Nowadays new examples are contributed on the relevant forum. You may find some tutorials there as well.

Examples for flat assembler g are gathered in dedicated thread on the message board.
