subroutine numtab	(		LUN,
			IDN,

Parameters

[in]	LUN	– integer: Internal I/O stream index associated with DX BUFR tables
[in]	IDN	– integer: Bit-wise representation of FXY value for descriptor
[out]	NEMO	– character*(*): Mnemonic associated with IDN
[out]	TAB	– character: Type associated with IDN 'B' = Table B descriptor 'D' = Table D descriptor 'C' = Table C operator 'R' = Replication descriptor 'F' = Replication factor
[out]	IRET	– integer: Positional index of IDN within internal Table B, if TAB = 'B' Positional index of IDN within internal Table D, if TAB = 'D' The X portion of the FXY value in IDN, if TAB = 'C' ((-1) * the Y portion of the FXY value in IDN), if TAB = 'R' and the replication is regular (i.e. non-delayed) 5, if TAB = 'R' or TAB = 'F' and the replication is 1-bit delayed 4, if TAB = 'R' or TAB = 'F' and the replication is 8-bit delayed (stack) 3, if TAB = 'R' or TAB = 'F' and the replication is 8-bit delayed 2, if TAB = 'R' or TAB = 'F' and the replication is 16-bit delayed 0, otherwise
