MvBits Intrinsic
................

     CALL MvBits(FROM, FROMPOS, LEN, TO, TOPOS)

FROM: `INTEGER'; scalar; INTENT(IN).

FROMPOS: `INTEGER'; scalar; INTENT(IN).

LEN: `INTEGER'; scalar; INTENT(IN).

TO: `INTEGER' with same `KIND=' value as for FROM; scalar;
INTENT(INOUT).

TOPOS: `INTEGER'; scalar; INTENT(IN).

Intrinsic groups: `mil', `f90', `vxt'.

Description:

   Moves LEN bits from positions FROMPOS through `FROMPOS+LEN-1' of
FROM to positions TOPOS through `FROMPOS+LEN-1' of TO.  The portion of
argument TO not affected by the movement of bits is unchanged.
Arguments FROM and TO are permitted to be the same numeric storage
unit.  The values of `FROMPOS+LEN' and `TOPOS+LEN' must be less than or
equal to `BIT_SIZE(FROM)'.
