The _ERRORLINE function returns the source code line number that caused the most recent runtime error.


Syntax

e% = _ERRORLINE


Description

  • Used in program error troubleshooting.
  • Does not require that the program use line numbers as it counts the actual lines of code.
  • The code line can be found using the QB64 IDE (Use the shortcut Ctrl+G to go to a specific line) or any other text editor such as Notepad.


Examples

Example: Displaying the current program line using a simulated ERROR code.

ON ERROR GOTO DebugLine 'can't use GOSUB

ERROR 250 'simulated error code

END
