BSAVE copies the contents of an area of memory to a file.
BLOAD loads a file created by BSAVE into memory.
 
BSAVE filespec$, offset%, length&
BLOAD filespec$[,offset%]
 
    - filespec$    For BSAVE, a file to which an area of memory (a
                   byte-for-byte memory image) is copied. For BLOAD,
                   a memory-image file created by a previous BSAVE.
    - offset%      For BSAVE, the offset of the starting address of the
                   area of memory being saved. For BLOAD, the offset of
                   the address where loading starts.
    - length&      The number of bytes to copy (from 0 through 65,535).
 
    - The starting address of the memory area saved or loaded is determined
      by the offset and the most recent DEF SEG statement.
