BlockShr - performs a block shift right of, count, bits.
Where the block is defined as:

The block is considered to be an ARRAY OF BYTEs

turn. The left most byte is considered the byte
located at the lowest address.
If you require an endianness SHIFT use
the SYSTEM.SHIFT procedure and declare the
block as a POINTER TO set type.
