◆ adn30()

character() function adn30	(	integer, intent(in)	idn,
		integer, intent(in)	ldn
	)

Convert an FXY value from its WMO bit-wise representation to a character string of length 5 or 6.

For an description of the WMO bit-wise representation of the FXY value, see ifxy().

This function is the logical inverse of function idn30().

Parameters

idn	- WMO bit-wise representation of FXY value
ldn	- Length of string to be returned; can be either 5 or 6 characters

Returns: adn30 - FXY character string

◆ cadn30()

subroutine cadn30	(	integer, intent(in)	idn,
		character(), intent(out)	adn
	)

Convert an FXY value from its WMO bit-wise representation to its 6 character representation.

This subroutine is similar to function adn30(), except that it always returns 6 characters, and it always returns its output as a call parameter instead of a function value, which in turn allows it to be more easily called from within a C language function.

For a description of the WMO bit-wise representation of an FXY value, see ifxy().

Parameters

idn	- WMO bit-wise representation of FXY value
adn	- FXY value

◆ idn30()

integer function idn30	(	character(), intent(in)	adn,
		integer, intent(in)	ldn
	)

Convert an FXY value from a character string to the WMO bit-wise representation.

For an description of the WMO bit-wise representation of the FXY value, see ifxy().

This function is the logical inverse of function adn30().

Parameters

adn	- FXY value; must be of length 5 or 6
ldn	- Length of adn; can be either 5 or 6 characters

Returns: idn30 - WMO bit-wise representation of FXY value

◆ ifxy()

integer function ifxy ( character*6, intent(in) adsc )

Convert an FXY value from its 6 character representation to its WMO bit-wise representation.

Per the official WMO BUFR regulations, an FXY value can be represented as a bit-wise integer in 16 bits, ordered from left (most significant) to right (least significant), and where the F value occupies the first 2 bits, the X value occupies the next 6 bits, and the Y value occupies the last 8 bits.

For example, if ADSC = '063022'

   F |     X     |      Y
   0 |     63    |      22
  0 0 1 1 1 1 1 1 0 0 0 1 0 1 1 0

then the corresponding ifxy

  = ( 2**13 + 2**12 + 2**11 + 2**10 + 2**9 + 2**8 +
      2**4 + 2**2 + 2**1 )

  = 16150

Parameters

adsc	- FXY value

Returns: ifxy - WMO bit-wise representation of FXY value

◆ igetfxy()

integer function igetfxy	(	character(), intent(in)	str,
		character*6, intent(out)	cfxy
	)

Search for and return a valid FXY number from within a character string.

The FXY number may be in format of either FXXYYY or F-XX-YYY within the input string, but it is always returned in format FXXYYY upon output.

Parameters

str	- input string
cfxy	- FXY number in format FXXYYY

Returns

0 normal return.
-1 could not find a valid FXY number in str

◆ nemtab()

subroutine nemtab	(	integer, intent(in)	lun,
		character(), intent(in)	nemo,
		integer, intent(out)	idn,
		character, intent(out)	tab,
		integer, intent(out)	iret
	)

Get information about a descriptor, based on a mnemonic.

Parameters

lun	- File ID associated with DX BUFR tables
nemo	- Mnemonic
idn	- WMO bit-wise representation of FXY value for descriptor for descriptor associated with nemo
tab	- Type associated with idn: 'B' Table B descriptor. 'D' Table D descriptor. 'C' Table C operator.
iret	- Return code: 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'. 0, otherwise

◆ numbck()

integer function numbck ( character*6, intent(in) numb )

Check an FXY number for validity.

Parameters

numb	- FXY value

Returns

numbck - Indicator as to whether numb is valid:

0 = Yes
-1 = No, the first character ("F" value) is not '0', '1', '2', or '3'
-2 = No, characters 2-6 ("X" and "Y" values) are not all numeric
-3 = No, characters 2-3 ("X" value) are not between '00' and '63'
-4 = No, characters 4-6 ("Y" value) are not between '000' and '255'
