How to add content to an array element?

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

Suppose I have an array:

@blah

@blah holds some values like the array it is.

$blah[0] holds "10".

How would I go about adding a string to $blah[0] so that it concatenates to:

"10.0.0.0"?

I've tried funky constructs like:

$blah[0] += ".0.0.0"; Or changed the += to . , but to no avail, since it is not a numeric.

Must be simple, I'm sure. :)

Thanks

Try `$blah[0] .= ".0.0.0";` or one of these ways `$blah[0] = $blah[0] . ".0.0.0";` or `$blah[0] = "$blah[0].0.0.0";`	[reply] [d/l] [select]

Thanks for OeufMayo, tilly and I thought mr.nick for pointing me to the obvious: `$blah[0] .= ".0.0.0";` --Jeroen/Asmodai	[reply] [d/l]

How about `@blah = qw( 10 0 0 0 ); $string = join '.', @blah;` [download] now $string should contain '10.0.0.0' What does this little button do . .`<Click>`; "USER HAS SIGNED OFF FOR THE DAY"	[reply] [d/l] [select]
