upb8()

subroutine upb8	(	integer(8)	nval,
		integer(4)	nbits,
		integer(4)	ibit,
		integer(4), dimension(*)	ibay
	)

This subroutine decodes an 8-byte integer value from within a specified number of bits of an integer array, starting at the bit immediately after a specified bit within the array.

It is similar to subroutine up8(), except that here IBIT is only an input argument, and the overall order of the arguments is different.

This subroutine will not work properly if NBITS is less than 0 or greater than 64, as determined via an internal call to subroutine wrdlen().

Parameters

[in]	IBAY	- integer(*): Array containing encoded value.
[in]	IBIT	- integer: Bit within IBAY after which to begin decoding NVAL.
[in]	NBITS	- integer: Number of bits to be decoded.
[out]	NVAL	- integer*8: Decoded value.
