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.

The $CHECKING metacommand turns C++ event checking ON or OFF.
|
|
|
|
|
|
''Syntax:'' $CHECKING:OFF
|
|
|
|
|
|
* The Metacommand does '''NOT''' require a comment or REM before it! There is no space after the colon.
|
|
* The OFF action turns event checking off and should '''ONLY be used when running stable, errorless code!'''
|
|
* The default $CHECKING:ON action is only required when checking has been turned OFF previously.
|
|
* When $CHECKING:OFF is used, all error code and the reporting code is removed from the EXE program.
|
|
* '''WARNING! Turning OFF error checking could create a General Protection Fault!'''
|
|
|
|
|
|
''Explanation:'' After every QB64 command a C++ check as follows is performed: If (qbevent){...
|
|
|
|
: Using [[ON TIMER (n)]] merely sets qbevent when appropriate, causing little/no difference to the speed your program runs. Unless you are using the QB64 direct meta-command to avoid this:
|
|
|
|
:::$CHECKING:OFF
|
|
|
|
:But turning checking off is only designed for 100% stable, error-less sections of code, where every CPU cycle saved counts. Such as in a software 3D texture mapper.
