GrabWeather Error

GrabWeather Error

[Peter]

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.
