The error could also mean that there isn't an array '@s340Strings' in your code. You may have typo'd the name of the array, or it may be a subset of that... if you wanted to print the array '@s' and then immediately the string literal '340Strings' (which would probably be bad, as it'll likely look like part of the last item in the array), you could do: `print "@{s}340Strings";` If you're just trying to print the literal string '@s340Strings', then either switch to single quotes, so it won't try to do variable expansion on you, or escape the @ with a \, as the error message suggested.

Among other things, it means you're running an old version of perl, and it's time to upgrade.	[reply]

Where do you define the array and assign to it because print "@s340Strings"; should work. Though if you want the contents of an array (an @array used in $scalar location will print the length of the array) then you want a for/foreach statement - like `print for @s340Strings;` Update: Interesting I've never run into that before, that actually would help quite a bit.

Putting an array in double quotes does not impose scalar context on the array; it does an implicit call to `join` using `$"` (default is a space) as the separator. Without the double quotes, `print` would print the contents using `$,` (default is empty string) as a separator. Caution: Contents may have been coded under pressure.	[reply] [d/l] [select]

an @array used in $scalar location will print the length of the array True, but this isn't the case. `perl -le '@A=qw(a b c d); print "@A"' a b c d` [download]	[reply] [d/l]

Another way to print the contents would be by using a module called Data::Dumper `!#/path/to/perl use Data::Dumper; print Dumper(@s340Strings); exit;` [download]	[reply] [d/l]

`my @s340Strings = qw("abc", "cdef","yxx","zzz"); print "@s340Strings\n"; prints: "abc", "cdef","yxx","zzz"` [download] Check your code. Please check if the array is a array of scalars or array of scalars and references. try hard-coding for test purpose the array value and see if you get past this line. That would mean the data is the culprit. Hope it helps Thanks! Sapna	[reply] [d/l]

That code is correct, but very confusing. You create a two element array, `$s340Strings[0] == "\"abc\","` and `$s340Strings[1] == "\"cdef\",\"yxx\",\"zzz\""`. That may be what you intended, but when I read it, it looks like you intend: `my @s340Strings = qw(abc cdef yxx zzz); # or my @s340Strings = ("abc","cdef","yxx","zzz");` [download] Just trying to clarify... -Bryan	[reply] [d/l] [select]
