Problem:

A .Net project reports a RTE 173 cbl_xmlio not found when executing an OPEN on an XML file

Resolution:

At the moment, we've only a workaround:

Add the directive:

$set ILPINVOKE(cblxmls.dll)

to those COBOL .Net programs, which need XML

You will need:

$set ILPINVOKE(cblxmlm.dll)

for mulit-threaded applications
