in thread parsing Win32::OLE::Variant

Hello:

Again thanks for your patience on this issue.

And I agree that the code you posted last should work. But it does not. However, taking another look at the Bloomberg documentation I found another function call that is simpler and does the same thing.

This code works.
use Data::Dumper; use Win32::OLE; use Win32::OLE::Variant; $blpData = Win32::OLE->new('Bloomberg.Data.1') or die "can NOT load t +he blpData" ; #print $blpData->Timeout . "\n"; $aSec = Variant(VT_BSTR, "VDE.A Equity"); #@tmpArray = ("PX_Last"); $aFields = Variant(VT_ARRAY|VT_BSTR, 5 ); $aFields->Put(0,"NAME") ; $aFields->Put(1,"ID_SEDOL1") ; $aFields->Put(2,"ID_CUSIP") ; $aFields->Put(3,"ID_ISIN") ; $aFields->Put(4,"ETF_UNDL_INDEX_TICKER") ; $bbData = Variant(VT_EMPTY,1) ; $bbData = Variant(VT_EMPTY, 1); $bbData = $blpData->BLPSubscribe($aSec, $aFields ); print "Error: " . Win32::OLE->LastError . "\n"; #print "Array Size: " , $bbData->Dim . "\n"; #print "Returned: " . $bbData->Get(0) . "\n"; print Dumper $bbData; for my $e (@$bbData) { print Dumper $e; my $d = @$e->[0]; print "Col Zero: " . @$e->[0] . " Col One: " . @$e->[1] . " Col + Four: " . @$e->[4] . " \n" ; print "Col Zero: " . $d . " \n" ; #foreach $tmp (@aDim) { # print $tmp } print "end" ;
It returns the following
Using an array as a reference is deprecated at tstblpSubscribeIIg.pl l +ine 37. Using an array as a reference is deprecated at tstblpSubscribeIIg.pl l +ine 39. Using an array as a reference is deprecated at tstblpSubscribeIIg.pl l +ine 39. Using an array as a reference is deprecated at tstblpSubscribeIIg.pl l +ine 39. Error: 0 $VAR1 = [ [ 'VANGUARD ENERGY ETF', 'B031N66', '92204A306', 'US92204A3068', 'MSCIEN' ] ]; $VAR1 = [ 'VANGUARD ENERGY ETF', 'B031N66', '92204A306', 'US92204A3068', 'MSCIEN' ]; Col Zero: VANGUARD ENERGY ETF Col One: B031N66 Col Four: MSCIEN end
However it has a minor issue. Using an array as a reference.
I tried many variations of syntax to access the arrays returned. The @$e-> is the only one that worked. Hoping you would provide me with clean syntax to parse the results returned.

thanks in advance.
