LINE INPUT will now use the faster method if passed a file handle that has been opened FOR BINARY. As such, the _BLINEINPUT command has been removed. qb64.bas now takes advantage of this for reading from '$include files, at least in Include Manager 1. Some tweaking of internal/source/main.txt was required to get things into a sane state, so I'm holing off changing the compiler any further so the auto-builder can make sure everything's smoothed over. Note: Everything should still compile as normal; I'm just being overcautious.

*'''[[Keywords currently not supported by QB64|Currently NOT supported in QB64!]]'''
|
|
* When line number tracing is on, the line numbers of statements are output immediately before they are executed.
|
|
* Use {{KW|TROFF}} to turn off line number tracing.
|
|
* Line number tracing only has an effect when programs are compiled with debugging code (<tt>BC.EXE /D</tt>).
