    // and character formatting in DsWord.
    // It creates a document and adds a paragraph of text to it.
    // It then splits the paragraph into two runs, and assigns different
    // font styles to the two halves of the text.
    // The GetRange() method enables easy pinpointing of locations in the document.

            // A Run is a contiguous fragment of a document with uniform formatting.
            // In our case, we have only one run so far, get it:

            // Set the size of the font on the whole run:
            run.Font.Size = 16;
            // A Text represents a contiguous fragment of text. It also belongs to a Run,
            // and cannot span multiple runs (a run though can contain several Text's).
            // Get the text object:
            Text text = run.GetRange().Texts.First;
            // Split the text into two halves (Split() returns the 2nd part):
            Text tIpsum = text.Split(lorem.Length / 2);
            // At this point, our run contains two Texts (two halves of the original text).
            // We now split the run into two corresponding runs so that we can
            // apply different formatting to the two texts:
            Run rIpsum = run.Split(tIpsum, InsertLocation.Before);
            // The 'text' was split into two halves, but the first half can still
            // be accessed via the 'text' variable.
            // A text's containing run can always be accessed via ParentRun.
            // We set the font of the first half to italic:
            text.ParentRun.Font.Italic = true;
            // and the font of the second half to bold:
            rIpsum.Font.Bold = true;
            // Done:
            return doc;
