ERR/ERL
=======

Function
--------

**ERR** and **ERL** return the error code and the line number at which
the error occurred respectively.

Syntax
------

| X = ERR
| Y = ERL

Example
-------

::

   10 GOTO 50
   20 A = ERR
   30 PRINT "Error Number";A;"at line";ERL
   50 ON ERROR GOTO 20
   60 B=A/0
   70 STOP

This example prints:

::

   Error Number 6 at line 60

due to the floating point error caused by an attempt to divide by zero.

Remarks
-------

ERR and ERL will always contain the codes of the last error, and will
often be used in conjunction with :doc:`error`.

These functions are often used in communications with the
:doc:`on-error` trap.

See :doc:`../basic-programming/errors-and-warnings` for actual
error numbers.

ERR defaults to zero until an error occurs.
