Function/Subroutine Documentation

upb()

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

This subroutine decodes an 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 upbb(), except that here IBIT is both an input and an output argument, and the overall order of the arguments is different.

Parameters

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

Remarks

• This subroutine is the logical inverse of subroutine pkb().
