Joining variables

[Diego Riaņo]

Hi Perl guys

I have another problem:

I have three variables working:
$var1
$var2 #and
$var3

I want to join these three variables in a new one, with some formar,
something like that:

$newvar will be $var1-$var2-$var3
for example if:

$var1=2000
$var2=08 #and
$var3=15

then

$newvar=2000-08-15

I hope someone can help me

Thanks in advances
