ERL Line Number of Most Recent Error
y = ERL
Returns the program line number at which the most recent error
occurred.
----------------------------------------------------------------------
Notes: If an error occurs on an unnumbered program line, then ERL
returns the last line number before the program line that
caused the error. If no line numbers are used at all, ERL
returns 0.
If the error occurs in an unnumbered program line, ERL
returns the last line number before the label.
