When this directive is used, BCX will create a trace log file on the C drive named: "c:\com_trace.txt" and log all operations with COM objects to this file.
Trace log file is overwritten with each start of program that has the $COM_TRACE directive enabled.
The purpose of trace log file is to identify bugs and solve COM parsing problems.
If you experience problems using COM objects in BCX or think that you have found a bug, it would be helpful to post contents of the trace-log file together with a sample program to the BCX support forum.
