/*		Constants Data Base
 *	contains constant name, offset, and hex value
 * -used by make file to generate table with name and address
 * -used by loader(s?) to download values to addresses
 *
 *	the address of a value is the specified offset added to:
 *	  s.p. constants:    0x400	"s...."
 *	  s.p. coeficients:  0x500	"c_s...."
 *	  d.p. constants:    0x600	"d...."
