BSAVE

Some versions of BASIC for home computers in the late 1970s and early 1980s include the command BSAVE (for "Binary Save") and the complementary BLOAD ("Binary Load"). Using the BSAVE command, a block of memory at a given address with a specified length can be written to disk as a file. Microsoft produced the BASIC interpreters that were bundled with the Apple II (1977), Commodore PET (1977), and IBM PC (1981) which included BSAVE and BLOAD. A BSAVE command is also part of ASCII's MSX-DOS2 Tools for MSX-DOS version 2. ==ColorBASIC==

On the Color Computer's ColorBASIC, those were named SAVEM and LOADM instead, with the M referring to machine code, showing that the primary intent was to load programs rather than data; the use of the B prefix to refer to binary indicates a broader view of the possible uses of the command. ColorBASIC uses a different format than GWBASIC. LOADM supports multipart content to be loaded in different places in RAM, which some programs do use, even though SAVEM supports only saving one part. The cassette equivalents were called CLOADM and CSAVEM. In ColorBASIC, the BRUN command is called EXEC instead. ==Video images==

image The BSAVED format is a device-dependent raster image format; the file header sometimes stores information about the display hardware address, and the size of the graphics data. The graphics data follows the header directly and is stored as raw data in the format of the native adapter's addressable memory. No additional information, such as screen resolution, color depth and palette information, bit planes and so on, is stored. ==See also==
