This is a better question for the VEE Reflector (http://www.agilent.com/find/vrf). This forum primarily support Network Analyzers.
You probably want to use the CALC:MARK<mark_num>:Y? query to read the marker data for the Y values and CALC:MARK<mark_num>:X? for the X values. You can use the TRAC:DATA? <trace_name> query to read the trace data back. I have attached an example that is integrated into VEE 7.5 that shows how to read trace data back and shows other settings.
