T QW 160 
Load the value of input word IW 128 into ACCUM 1.
  Shift the bit pattern in ACCUM 1 four positions to the right.
Transfer the result (contents of ACCUM 1) to output word QW 160.
Numeric Example
The value 352
10
 is stored in IW 128.  
Shift the corresponding bit pattern
in ACCUM 1 four positions to the
right to divide the value 352
10 
by
2
4 
= 16.
