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). See Bit_Size Intrinsic.
