I have tried to find any info on this in the faq and the documentation but so far I have found none. If this is a faq and I just haven't looked well enough, please feel free to hit me with verbal abuse in personal e-mail. I have tried to get tr to work as in e.g. $something =~ tr/0-9A-Za-z \n//c I know that character ranges on a Mac behave strangely, but in my naivity I believed that straight ASCII (as in the example above) would work. Is there anywhere where I can find the collected experiences with character ranges, tr, and the like? espen ------------------------------------------------------------------------ Espen Ore Persons.: 96 81 21 81 Tel: + 47 55 58 28 65 Norwegian Computing Centre for the Humanities Fax: + 47 55 58 94 70 Harald Haarfagresgate 31 Espen.Ore@hd.uib.no N-5007 Bergen, NORWAY
