It would be helpful to learn how to add two string variables together in a script.

Example:

$firstvar = "Hello "
$secondvar = "world"

How do you make a new variable with "Hello world" using $firstvar and $secondvar

In GWBASIC I can simply do this:

Hi$ = Firstvar$ + SecondVar$

How does one do this in Perl?

Hello again,
all you need to do for this is:
$Hi = "$FirstVar $SecondVar";

Actually, the concatenation operator in perl is a ., however joining two strings by using variable expansion inside quotes is the more common method.

$hello = "hello ";
$there = "there";
$hi = $hello . there;

You can see why this would not be the simpliest method since you need to leave blank spaces if you want your $hi string to be "hello there" and not "hellothere."

Unquoted string "there" may clash with future reserved word at thewitt line 3.

#And to complete the list:
$hi = join("",$firstvar,$secondvar);
$hi = pack("a*a*",$firstvar,$secondvar);
($hi = $firstvar).=$secondvar;
substr($hi=$secondvar,0,0)=$firstvar;
($hi = $firstvar)=~s/$/$secondvar/;
#hmm, any more?
