BSAVE

BSAVE and BLOAD are commands in many varieties of the <a href="/facts/BASIC/ELoTkjnM">BASIC</a> programming language. BSAVE copies <a href="/facts/Random_access_memory/DuD4bxh6">RAM</a> to a <a href="/facts/Binary_file/ysttM8hh">binary file</a>, and BLOAD copies the contents of the file to RAM. The term "BSAVE image" could mean any of various <a href="/facts/Raw_image_format/1T6qygdz">raw image formats</a> of <a href="/facts/Video_display_controller/ISm9E6Nc">video display controllers</a>, or more generally any file containing the raw contents of a section of memory.
Some platforms provided a BRUN command that, after loading the file into memory, would immediately attempt to <a href="/facts/Execution_(computing)/1fyfGMFm">execute</a> it as <a href="/facts/Machine_code/bgdQ1Fxf">machine code</a>.
There is no file compression, and therefore these files load very quickly and without much programming when displayed in native mode.
BSAVE files were in general use as a file format when the <a href="/facts/IBM_PC/yhcJGMPL">IBM PC</a> was introduced. It was also in general use on the <a href="/facts/Apple_II/se82CNvK">Apple II</a> in the same time period. Although the commands were available on the <a href="/facts/Commodore_PET/08R12Xk4">Commodore PET</a> line, they were removed from the later (and more popular) Commodore 64 and VIC-20 computers. In 1985 the <a href="/facts/Commodore_128/vKlttwT1">Commodore 128</a> was released with <a href="/facts/Commodore_BASIC/wYrzVk3f">Commodore BASIC</a> version 6.9 which restored the BSAVE and BLOAD commands.
