how to extract a set of specified values by using HFSS8?

hi,everyone:

Now I am using HFSS_V8 for calculation of a microstrip antenna. The antenna is very simple, just consisting of infinite ground plane, substrate and rectangle radiator fed by coaxial!

What I need to deal with is to extract the values of current at a specified point on the radiator, and I know that this can be done by compiling a file of HFSS_Macro.

But I do not know how to do using macro for I know little about the compiling of HFSS_macro!

Who can tell me what I should do?

You can find Macro Guideline to learn!
But I don't know where can download it!
Who knows?

In @nsoft Designer, Macro doesn't exist!
