You're asking for a boolean OR. Any non-zero in C is boolean TRUE. A boolean operator that returns true returns 1, IIRC. I'm not sure what the problem is. If you want to return one or the other of a couple of options depending on whether the first is true, you want: #define is4rafsi(str) (monmapti("CVCC",str) ? monmapti("CVCC",str): monmapti("ICVC",str)) IIRC. -Robin -- http://www.digitalkingdom.org/~rlpowell/ *** I'm a *male* Robin. .i le pamoi velru'e zo'u crepu le plibu taxfu .i le remoi velru'e zo'u mo .i le cimoi velru'e zo'u ba'e prali .uisai http://www.lojban.org/ *** to sa'a cu'u lei pibyta'u cridrnoma toi
