40 SHUFFLE KEY

SHUFFLE KEY


Shuffle is the opposite of split. The top half of
memory becomes the odd bytes, the bottom
half the even bytes. Every byte in memory is
moved, except the first and last - 0000 and
FFFF.
Using the and keys you can also elect to
SHUFFLE 128k 256k or 512k bytes.

If PROMS are to be loaded into USER RAM
and the code sent to a remote computer
through the RS232 interface, in a 16 or 32 bit
system it must be combined so that the bytes
are successive. This can be achieved by
loading the different PROMS to different blocks
of memory and shuffling.
