Function/Subroutine Documentation

subroutine pkb	(		NVAL,
			NBITS,
		dimension(*)	IBAY,
			IBIT
	)

This subroutine encodes an integer value within a specified number of bits of an integer array, starting at the bit immediately after a specified bit within the array.

Author

Parameters

[in]	NVAL	– integer: Value to be encoded
[in]	NBITS	– integer: Number of bits of IBAY within which to encode NVAL
[out]	IBAY	– integer(*): Array containing encoded NVAL
[in,out]	IBIT	– integer: Bit pointer within IBAY On input, IBIT points to the bit within IBAY after which to begin encoding NVAL. On output, IBIT points to the last bit of IBAY which contains the encoded NVAL.

Remarks

• This subroutine is the logical inverse of subroutine upb().
• This subroutine will not work properly if NBITS is greater than the number of bits in an integer, as determined via an internal call to subroutine wrdlen(). In such cases, the user should switch to a compiled version of the BUFRLIB software which has a larger integer size.
