Agreed. You might go and name all your scripts/executables *.plx and reserve *.pl for OLD "P"erl "L"ibraries, but you definitely should not create new libs. Learn to create fullblown modules (*.pm). > > Lacking some truly compelling reason, it strikes me as a bad idea to > > veer off on an unfamiliar and non-standard model.

The *.pl was interpreted by perl.exe, while *.plx was interpreted by perlIS.dll (In-process Perl interpreter for MS IIS). I know the Installer used to map those two extensions this way, I'm not sure what does it do now though (not using Perl for CGI currently). Using .pl for Perl Libraries is considered long deprecated. Jenda P.S.: I use another extension, .gpl. I have this extension mapped to wperl.exe ... the consoleless interpreter.
