ERL - mkilgore/QB64pe GitHub Wiki

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

lastErrorLine& = ERL

• 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.
