Hello fellow monks,
I was wondering if there is a way to do the following.
Say you have 2 strings, like:
$a = 'PF01389    6    218    1    255    430.09';
$b = 'PF00691    PF01389';

You can notice that these 2 strings have PF01389 in common. So, I wanted to knows if there is a way of checking for values inside one string that are equal with values in the other.
I tried using:
if ($a=~/$b/ or $b=~/$a/)
{print "correct";}

but it doesn't work, because it searches for the whole $a or $b and not parts of them.
Any suggestions?
