The BBC and Master Computer Public Domain Library

This page contains all of the error messages issued by the BASIC4r32 ROM. A number surrounded by pointed brackets, i.e. <138>, indicates reference to a BASIC KEYWORD. These references are automatically expanded into the actual keywords when BASIC prints the error message. The Keywords relating to each number are shown on the character table page.

Note: The error messages "Bad Program" and "Failed at" are not included, as they aren't really error messages, because they are not handled via the BRK vector. Instead, the BASIC ROM just displays these texts directly on the screen, without causing a BRK event to occur.

The Error Messages are listed in Numerical order by ERR number:
