The TROFF statement turns off the program trace. The TRON and TROFF statements only display line numbers when compiled with the Debug option or the /D option on the BC command line. Note: The debugging features of the QuickBASIC environment make these statements unnecessary. See the ◄Debugging Keys► for more information.
