rob-au, You are right, of course, that the directory gets tacked onto the "left end" of the @INC. My error. I am having some success with your FindBin suggestion........But my experimentation seems to suggest that the web hosts (buggy) CGI.pm gets picked instead of mine in mylib. The only way I've made some progress is by renaming my CGI.pm as CGI279.pm & specifying the line "use CGI279" in my Perl script........Due to semester starting (I teach), I will have to suspend my efforts for now. But thanks for the useful guidance. Tom
