ERL system variable

Purpose | Return the last line number encountered before the most recent error.
Syntax | nline = ERL
Remarks | Return the last (most recent) line number that was encountered before the most recent run-time error, within the current Sub, Function, Method, or Property. With ERL, line numbers are of the traditional-basic line numbering variety, not the physical source code line.
