The [[ERL]] function returns the closest previous line number before the last error.


{{PageSyntax}}
: ''lastErrorLine&'' = [[ERL]]


{{PageDescription}}
* Used in an error handler to report the last line number used before the error.
* If the program does not use line numbers, then ERL returns 0.
* Use [[_ERRORLINE]] to return the actual code line position of an error in a QB64 program.
