Error Codes
===========

Overview
~~~~~~~~

Celtic does its best to prevent errors. However, if something goes wrong with running a function, Celtic will return an error code. This can be from lack of memory, an incorrect argument, or something else.
Keep in mind that Celtic might not always detect the exact error, or realize that there is one in the first place. You can use the error codes to help with the debugging process.
This page also contains TI-OS errors and the corresponding values returned in the ErrorHandle command.
