     IBits(I, POS, LEN)

IBits: `INTEGER' function, the `KIND=' value of the type being that of
argument I.

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

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

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

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

Description:

   Extracts a subfield of length LEN from I, starting from bit position
POS and extending left for LEN bits.  The result is right-justified and
the remaining bits are zeroed.  The value of `POS+LEN' must be less
than or equal to the value `BIT_SIZE(I)'.  Note: Bit_Size Intrinsic.
