The set
specified by Rl and ending with the register speci
fied by R3 is loaded from the locations designated by
the second-operand address.
The storage area from which the contents of the
general registers are obtained starts at the location
designated by the second-operand address and con
tinues through as many locations as needed. The
general registers are loaded in the ascending order of
their addresses, starting with the register specified by
R 1 and (;ontinuing up to and including the register
specified by R3, with register

The absolute value of the second operand is placed
in the first-operand location.
The operation includes complementation of nega
tive numbers; positive numbers remain unchanged.
An overflow condition occurs when the maximum
negative number is complemented; the number re
mains unchanged. The overflow causes a program
interruption when the fixed-point overflow mask bit
is one.
