Syntax
VAR16 >>= N |
shift VAR16 right by N |
VAR32 >>= N |
shift VAR32 right by N |
PROD >>= N |
shift PROD (product reg.) right by N |
| Operands | VAR16: integer variable |
VAR32: long or fixed variable
PROD: 48-bit product register
N: shift factor
Binary code
| Description | The operand is right shifted with the specified number of bits (N). High order bits are sign-extended and the low order bits are lost. If the operand is PROD, the entire 48-bit product register is right shifted. |
| Execution | Variable = Value of variable shifted to right with N bits |
