For your scenario, I would do the following steps:
1. Create a new Delimited data source and provide the delimiter in the 'Column delimiter'.
1. Specify a below regular expression in the "Start of data zone delimiter" that would skip the first six lines of the delimited file.
By doing the above steps, I would be able to create a base view that would skip the commented lines.
For more information, you can have a look at the section [Delimited File Sources](
) of Virtual Dataport Administration Guide.
Hope this helps!!
