I had a go at getting that to work with preprocessor magic but I don't think it's possible (I'm no CPP guru though). Actually, how about.. #define FOO "\070" #define getOrd(x) (x)[0] ? I only compiled it on a PC so I don't know if it would be optimised down to what you expect but I think it would be. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
