Commands sometimes generate errors on certain inputs. They usually display as an error message, halting the running program, but if the error occurs in an IFERR block, the THEN clause gets ran, placing the error code in Ans.

The error code is an integer. To get the error message from the error code, use STRINGFROMID like so:

EXPORT error_code(x)
BEGIN
	STRINGFROMID(654+x)
END;
