i am very very new to perl and need some help !. I have the following lines in a file: 
SYMM     1/8 - X, 1/8 + Y, 1/8 + Z
SYMM     1/6 - X, 1/6 + Y, 1/6 + Z
SYMM     1/4 - X, 1/4 + Y, 1/4 + Z
SYMM     1/2 - X, 1/2 + Y, 1/2 + Z

..and I am using the following script below to initially undef SYMM and store the lines in the 4 variables $symmetry. Then by numerous splits (excuse the temporary and crude names of the variables!) I isolate the individual fractions and calculate their values (i.e 1/8)=($frac1[0]/$frac2[0])=(0.125). Question: How would I modify the script below to give me a loop which prints out of all the fraction values. At the moment I can only get print out of 0.5 0.5 0.5 for the last line as the others are overwritten. Hope this is clear ! Any takers ! cheers 
   if (/SYMM/)
   {
    (undef, $symmetry[$i]) = split /SYMM\s+/;
    ($symm[$i], $symm[$i], $symm[$i]) = split /,\s+/, $symmetry[$i];
    $i++;
       next LOOP;      
   }
}
close (IN);

    foreach $i(0..$symm) {            
    if ($symm[$i] !~ /\d{1}/) {                    
        ($tmp2[$i], $tmp3[$i]) = split /\s+/, @symm[$i];        
            $tmp1[$i] = 0;    
    }else{
        ($tmp1[$i], $tmp2[$i], $tmp3[$i]) = split /\s+/, @symm[$i];
    }
    ($frac1[$i], $frac2[$i]) = split (/\//, @tmp1[$i]);     
    }

print @value[0] = ($frac1[0]/$frac2[0]); print "\n";
print @value[2] = ($frac1[1]/$frac2[1]); print "\n"; 
print @value[3] = ($frac1[2]/$frac2[2]);
