in reply to Re^2: replace at the begining
in thread replace at the begining

My mistake - \s means a whitespace character, which can be several things (a space, a tab, etc.). So it makes no sense as a substitution character (of the various options, which should perl use?). 
map{$a=1-$_/10;map{$d=$a;$e=$b=$_/20-2;map{($d,$e)=(2*$d*$e+$a,$e**2
-$d**2+$b);$c=$d**2+$e**2>4?$d=8:_}1..50;print$c}0..59;print$/}0..20
