-C ID=110 for PI0, ID=220 for ETA, etc.
-C
-C Baryons--
-C I<=J<=K in general
-C J<I<K for second state antisymmetric in (I,J), eg. L = 2130
-C
-C Other--
-C ID=1,...,6 for quarks
-C ID=9 for gluon
-C ID=10 for photon
-C ID=11,...,16 for leptons

-C
-C Incomplete meson multiplets used in b decays:
-C ID=10121 A1+(1260)
-C ID=10111 A10(1260)
-C ID=10131 K1+(1270)
-C ID=10231 K10(1270)
-C ID=30131 K1*+(1400)
-C ID=30231 K1*0(1400)
-C ID=132 K2*+(1430)
-C ID=232 K2*0(1430)
-C ID=10110 F0(980) (mass = 1000 to allow K+K- decay)
-C ID=112 F2(1270)
-C ID=10441 PSI(2S)
-C ID=20440 CHI0
-C ID=20441 CHI1
-C ID=20442 CHI2
-C
-C Diquarks--
-C ID=+/-IJ00, I<J for diquark composed of I,J.
-C
-C INDEX is a sequence number used internally
-C
-C Ver. 7.03: Make more robust by returning INDEX = 0 for
-C bad ID codes. Does not check for valid baryons, e.g.,
-C uuu with J = 1/2. Test on LABEL(1:3) = 'ERR' for this.
