You might want to look over perlretut and perlre. In order to use the $1,$2,$3 ... variables you have to have a matching regular expression and you need capturing parens. Anyhow if all lines are in that format you can use:

($var1, $var2) = ($1,$2) if /(\S+)\s+(\S+)/;

if the lines are not the same throughout the file and you and you need to be more specific:

($var1,$var2) = ($1,$2) if /^\s{9}(\S+)\s{10}(\S+)/;
