[amibroker] Extremely Sharp Eye Required to Find Error

["Ken Close" <ken45140@xxxxxxxxx>]

The following code does not produce an error:

 

ab = CreateObject("Broker.Application");

 

Fn3   =  ParamStr( "Fund3", "WTM24");

Fn4   =  ParamStr( "Fund4", "FDRXX");

Fn5   =  ParamStr( "Fund5", "WTM25");

stock3 = ab.Stocks(Fn3); 

stock4 = ab.Stocks(Fn4);

stock5 = ab.Stocks(Fn3);  

FName3 = stock3.FullName;

FName4 = stock4.FullName;

FName5 = stock5.FullName;

 

The following produces an error in the last shown line:

 

ab = CreateObject("Broker.Application");

 

Fn3   =  ParamStr( "Fund3", "WTM24");

Fn4   =  ParamStr( "Fund4", "FDRXX");

Fn5   =  ParamStr( "Fund5", "WTM25");

stock3 = ab.Stocks(Fn3); 

stock4 = ab.Stocks(Fn4);

stock5 = ab.Stocks(Fn5);  

FName3 = stock3.FullName;

FName4 = stock4.FullName;

FName5 = stock5.FullName;  <<<< Line with error

 

Error Msg = COM object variable is not initialized or has invalid type (valid COM object handle required)

 

Look closely. The definition of stock5 changes subtley from the no error state to the error state.

 

I used copy/paste for the statements, then changed the variables.  I cannot get rid of the error message.  Fn5 always has contained a valid statement and a valid fund in the default position of the ParamStr statement.

 

Any ideas?

 

Ken
