How could I add Existing Variables into a Paragraph using ExtendScripts?

Hi,

Based on a specific paragraph tag, I would like to add an existing variable (Name and Fmt) as part of the paragraph's text. I am able to add strings as part of paragraph texts at the moment.

I was looking up extend scripts to do this, however I am quite not sure how to add a variable. I could only find instances of updating variable values and so on.

Any help would be appreciated.

Giving a brief overview of my intention: (For example; Variable = "Part Number: 0x404"

                            var newpgf = doc.NewSeriesObject(Constants.FO_Pgf, pgf);

                            var attribute= doc.GetNamedObject(Constants.FO_VarFmt, "Variable");

                            var textLoc = new TextLoc();

                            textLoc.obj = newpgf;

                            textLoc.offset = -1;

                                                               doc.AddText(textLoc, "( ");

Something like this:                            -> doc.AddText(textLoc, attribute.Fmt);       // Not Sure how to do this, possibly link the variable text range to this Text Location?

                                                               doc.AddText(textLoc, " )");               

Expected Paragraph:

                                             <Previous Para>

          new Para:                    (Part Number: 0x404 )

Thanks,
Sebin
