Use:  
void irco_praxname_c( 
	fint	*coor, 		I	coordinate system number
	fint	*prid, 		I	projection type number
	fchar 	lname,		O	name of the 'longitude' axis
	fchar 	bname )		O	name of the 'latitude' axis

USE   For the combination of coordinate system and projection type
      identification names are returned which are valid in FITS.
      The names which are returned,  represent the coordinate axis
      (l/bname: 4 char) padded with a projection type (pname: 4 char).
