Hello, I installed Active State 5.6.1 rev 633 on a Win2K box. When I try to run the following progralm I get the error 
C:\Documents and Settings\dln1\My Documents\PERL>perl excel.pl
Can't call method "Open" on an undefined value at excel.pl line 16.

The source is: 
use OLE;

$xlfile ='Book1.xls';

##### OLE - Excel Connection

# Create OLE object - Excel Application Pointer
$xl_app = CreateObject OLE 'Excel.Application' || die $!;

# Set Application Visibility
# 0 = Not Visible
# 1 = Visible
$xl_app->{'Visible'} = 0;

# Open Excel File
$workbook = $xl_app->Workbooks->Open($xlfile);

# setup active worksheet
$worksheet = $workbook->Worksheets(1);

# retrieve value from worksheet


$cellA1 = $worksheet->Range("A1")->{'Value'};
$cellB1 = $worksheet->Range("B1")->{'Value'};

print "Cell A1 = $cellA1";


$worksheet->Range("A1")->{'value'} = "01aBcD2";
$cellA1 = $worksheet->Range("A1")->{'Value'};
print "\nCell A1 = $cellA1";
$cellA1 =  uc $cellA1;
print "\nCell A1 = $cellA1";

# Close It Up
$xl_app->ActiveWorkbook->Close(0);
$xl_app->Quit();

I verified the file exists and can be opened by excel. Any assistance in diagnosing the problem would be appreciated. Thanks, Daniel
