Added new _STRCMP and _STRICMP commands for quick string comparisons. Cleaned up QB64 to finish removing the QUI (quick user insert) code and folders. Altered UCASE and LCASE routines to be faster in some situations for us.

{{KW|BLOAD}} loads a binary graphics file created by {{KW|BSAVE}} to an array.

::: '''BLOAD {{Parameter|Filename$}}, {{KW|VARPTR}}({{Parameter|ImageArray%(index)}})'''

{{PageDescription}}
|
|
* {{Parameter|Filename$}} is the name of the file that the image should be saved to.
|
|
* {{Parameter|ImageArray%(index)}} is the Integer array that holds the image you want to save.
|
|
* There MUST be an Integer array of adequate size (up to 26K) to hold the graphic data!
|
|
* A {{KW|DEF SEG}} pointing to the array is required. {{KW|DEF SEG}} = {{KW|VARSEG}}(ImageArray%(index))
|
|
* {{Parameter|index}} is the starting image element of the Array. Can also include RGB color settings at the start index.
|
|
* Fullscreen images in {{KW|SCREEN}} 12 require 3 file {{KW|BLOAD}}s. A 26K array can hold 1/3 of screen.
|
|
* Custom RGB color settings can be embedded(indexed) at the start of the image array.
|
|
* {{KW|BLOAD}} Can be used to load any arrays that was saved with {{KW|BSAVE}}, not just graphics.
|
|
* Array sizes are limited to 32767 Integer elements due to use of {{KW|VARPTR}} in QB and '''QB64'''!.
|
|
* '''QB64''' can load larger arrays directly to and from binary files using {{KW|PUT}} # and {{KW|GET}} #.
