Well, no. I was looking for a python-like substring function. Anyway, thanks for the (substring "ciao" 0) trick, it is a very handy method to trim strings on the left (not documented in the wiki, btw): (substring "ciao" 1) => "iao" In my ideal world, there would room also for that: (substring "ciao" 0 -1) => "cia" but I know, I know... it will never happen :-( Regards, Michele _______________________________________________ Chicken-hackers mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/chicken-hackers
