What I want is the variable $BEGINREGEX to contain a string like so: ^<!-- // begin of news1 // !-->$ or ^<!-- // begin of news2 // !-->$ The digit after the "news" should be whatever $no is set to at that point in the script. > > my $no = 1; > > my $bla = eval($BEGINREGEX); > > print "$bla\n"; > > > > $bla is empty for some reason. > > You probably do not want to use eval here, or at least not in this way. What should I do then? It's simple, really. I am sure I am just making a stupid mistake. my $BEGINREGEX = "sprintf(\"^<!-- // begin of news\$no // !-->\$\")"; my $no = 99; my $bla = eval($BEGINREGEX); print "regex string: $bla\n"; What should be printed: regex string: ^<!-- // begin of news99 // !-->$ But it isn't, so what am I doing wrong here?
