Elemental Intrinsic Function (Generic): Sets one bit to 1.
Syntax
result = IBSET (i, pos)
i
(Input) Must be of type integer.
pos
(Input) Must be of type integer. It must not be negative and it must be less than BIT_SIZE(i).
The rightmost (least significant) bit of i is in position 0.
Results
The result type is the same as i. The result has the value of the sequence of bits of i, except that bit pos of i is set to 1.
For more information, see Bit Functions.
The model for the interpretation of an integer value as a sequence of bits is shown in Model for Bit Data.

Examples
IBSET (8, 1) has the value 10.
If V has the value (1, 2, 3, 4), the value of IBSET (POS = V, I = 2) is (2, 6, 10, 18).
The following shows another example:
INTEGER I
I = IBSET(8, 2) ! returns 12 = 1100
