Service Virtualization

I am trying to write the response from a VS call to a delimited file. If say the response from VS call is in a variable called VarA, and I choose the "Write to Delimited File" step to write out the contents of VarA, I still get a header line that says "Key". Is there a way to avoid the header line? Also, is there a way to write the variable as is, without enclosing in quotes?

I guess I was not using the "write to delimited file" feature, the way  it is meant to be used. I changed my implementation to achieve my desired result.
