BTest(I, Pos)
BTest: LOGICAL(KIND=1) function.
I: INTEGER; scalar; INTENT(IN).
Pos: INTEGER; scalar; INTENT(IN).
Intrinsic groups: mil, f90, vxt.
Description:
Returns .TRUE. if bit Pos in I is
1, .FALSE. otherwise.
(Bit 0 is the low-order (rightmost) bit, adding the value or 1, to the number if set to 1; bit 1 is the next-higher-order bit, adding or 2; bit 2 adds or 4; and so on.)
See section Bit_Size Intrinsic, for how to obtain the number of bits in a type. The leftmost bit of I is `BIT_SIZE(I-1)'.
