Limitations The specified source bits must be in the same data area.
The specified destination bits must be in the same data area.
Description When
the execution condition is OFF
, XFRB(62) is not executed. When the exe
-
cution
condition is ON, XFRB(62) copies
the specified source bits to the speci
-
fied destination bits. The two rightmost digits of C specify the starting bits in S
and
D and the leftmost two digits indicate the number of bits that will be copied.
