If you have spent any time programming for the Atari 8-bit computers then you have experienced error codes generated from typos or bad code. There is a nice page on the Atari Wiki which lists error codes for several common programming languages and DOS. These are worth taking a moment to explore.


Navigate to the Atari Wiki error codes page and browse the list in a PDF file.

Here is a guide to error codes from Page 6 magazine along with part 2.

The Atari BASIC reference manual also has a list of error codes.

The famous Purple Book also has a list of error codes in Appendix A.


I had fun looking through this list. Some errors certainly brought back memories from coding back in the day. I am guessing error 138 (Device Timeout) is one many modern Atari computer owners encounter when there is a problem with a peripheral. Below is an example error I engineered in BASIC. May your Atari experience be error free!
