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


Syntax:

result& = ERL


Description:

  • 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.


Example: Using a fake error code to return the line number position in a program.

ON ERROR GOTO errorfix 1 ERROR 250 ERROR 250 5 ERROR 250 END errorfix: PRINT ERL RESUME NEXT

1 1 5
