I am wondering if you could have more then one External Data file in a OnJobStart rule and if so what is the limit. I was able to link to one "test1.txt" using a sample I found in the forums (below), but how would I add two files "test1.txt" and "test2.txt"?
//Link to the external data file.
//The '\t' is used to indicate TAB delimited data in this external data file
externalDF = new ExternalDataFileEx('test1.txt', '\t');
if(externalDF.valid != true)
{
Print('Failed to link to the external data file in OnJobStart');
}
