Hi,

If I invoke GrabWeather I get the following error:

Use of uninitialized value in concatenation (.) or string at
/usr/local/bin/GrabWeather line 200.

Line 200 reads:

print TmpFile "$SkyConditions\n";

before that there are lines referring to sky condition:

-----------
my ($StationInfo, $UpdateTime, $SkyConditions, $CodedMETAR);

while (<TmpFile>)
{
chop;

if ($Flag == 0) { $StationInfo = $_; };
if ($Flag == 1) { $UpdateTime = $_; };
if (/^Sky conditions:/)
{
$SkyConditions = $_;
$SkyConditions =~ s/Sky conditions: (.*)/$1/;
}

------------

Does anyone know how to fix this?

In the meantime I just uncommended line 200.

GrabWeather works just the same.

Thanks & regards

Peter -- Since the error is from an unitialized variable, the obvious
thing to try is to initialize it with a harmless default value. Add a
line something like this one:

> my ($StationInfo, $UpdateTime, $SkyConditions, $CodedMETAR);

$SkyConditions = " " ;

> while (<TmpFile>)

I'm assuming this is Perl code; it looks like Perl.
