note ysth <blockquote><i>-a only works in combination with -n or -t</i></blockquote> I assume this is a typo and Abigail meant -n or -p. <p> Actually, even without -n or -p, the -a switch does have the very minor effect of creating @F, so that referring to it won't get you a <code>Name "main::F" used only once: possible typo</code> warning. (And *F{ARRAY} will give a reference to @F even if no @F is mentioned anywhere, instead of the usual undef.) &nbsp; These could be construed as a bug. 324749 324839
