in reply to Padding with \s

you could use concatenation ("the dot operator") : 
my $crypticString="LR20SR37PD30LR23CR23BT01H";
my $acceptableLength=40;
my $paddedString =$crypticString . " " x 
    ($acceptableLength - length ($crypticString));
print "'$paddedString'";

Also, using \s to indicate " " might be confused with the character class \s (which also includes newlines and tabs).
