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.

* Can use [[STEP]] keyword for graphics coordinates relative to a previously placed objects.
|
|
* Creates a colored line from coordinate1 to coordinate2 if the box options(B or BF) are omitted. Can be drawn partially offscreen.
|
|
* Creates a colored box outline if the '''B''' option is used.
|
|
* Creates a color filled box if the '''BF''' option is used.
|
|
* Style is any [[INTEGER]] value from 0 to 32767. It creates dashed lines or box outlines. The Box comma is required with style even when not creating a box. The lines are created where the style value's bits are on. '''BF cannot be used with style.'''
|
|
* '''LINE can be used in any graphic screen mode, but cannot be used in the default screen mode 0 as it is text only!'''
