Keef has asked for the wisdom of the Perl Monks concerning the following question:

I have a two variables, how do I justapose them so they create a 3rd variable. Like so:

$var1 = "cream";
$var2 = "coffee";
$var3 = $var2 " & " $var1;
print $var3 # returns "coffee & cream"

The string concatenation operator is . Applying this operator is left as an exercise.	[reply]

I'm not sure I understand what you mean by juxtapose but this works for me- `$var1 = "cream"; $var2 = "coffee"; $var3 = $var2 . " & " . $var1; print $var3 # prints "coffee & cream"` [download] which uses the '.' operator to concatenate the strings, is that what you wanted? -- my $chainsaw = 'Perl';	[reply] [d/l]

To quote the Beasty Boys, "I like my sugar with coffee & cream". Moving on... `$var3 = "$var1 & $var2"; $var3 = $var1 . " & " . $var2; $var3 = join ' & ',$var1,$var2; undef $var3; $var3 .= $_ for $var1 =~ /./sg,' ','&',' ',split//,$var2;` [download] The choice of WTDI is up to you =) MeowChow s aamecha.s a..a\u$&owag.print	[reply] [d/l]

The usual answer is to use interpolation. `print "$var2 & $var1"; # Prints "coffee & cream"` [download] That is why all of those funny little symbols are used, to make it easy to drop variables directly in strings...	[reply] [d/l]
