is a string (length 255) which returns a description of the error.
error
is an integer which contains the error number you want the text about.
This external returns a string containing the description of the error based on the long integer parameter which contains the error number (from the Error 4D variable or from externals).
If an error occured while looking for the error text or the error number is unknown the text 'Unknown error (err)' is returned (the 'err' is replaced by the error number).
All positive error numbers are internal for 4D and the description is obtained from a STR# resource with ID 29.
The zero and all negative error numbers are from the system software and are stored using a special scheme in STR# resources. The ERR# resource countains the list of STR# resource IDs and the range of error numbers of which they contain the text.
This scheme was designed by and used with permission from Michael Hecht (Michael_Hecht@mac.sas.com). He entered most of the text and I added about 10 STR# resources (using the 'System Errors 7.0.1' application by Pete Corless).
