# IBSET

Elemental Intrinsic Function (Generic): Sets one bit to 1.

result = IBSET (i,pos)

i | (Input) Must be of type integer or of type logical (which is treated as an 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 and kind are 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.

Specific Name | Argument Type | Result Type
--- | --- | ---
BBSET | INTEGER(1) | INTEGER(1)
IIBSET1 | INTEGER(2) | INTEGER(2)
JIBSET | INTEGER(4) | INTEGER(4)
KIBSET | INTEGER(8) | INTEGER(8)
1Or HBSET.

## Example

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
