No, that's not the same. It still outputs the empty lines. ($q=q:Sq=~/;[c](.)(.)/;chr(-\|\|-\|5+lengthSq)`"S\|oS2"`map{chr \|+ord }map{substrSq`S_+\|`\|}3E\|-\|`7**2-3:)=~y+S\|`+$1,++print+eval$q,q,a, [download]	[reply] [d/l]

In defence of my oh-so-cool perl snippet - `l` is less typing than `sed -ne` on subsequent calls with the same file, I need not specify the file as argument it is the one script which needed a `CHECK` block And that's pretty much all about that. If I were better at typing, two of them three arguments would be quite pointless ;-) perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'	[reply] [d/l] [select]
