Hi Shashikanth,
We can achieve it through floating fields. The above Image is cropped from the PDF output I have developed.
There are Few steps to achieve it.
Will try to include as many Images posible. 
Step 1: From the Object Library Please drag and drop the Text Object on to the Body page.
Step 2: In the Hierarchy view, select the Text Object and wrap it into a Sub Form.
Step 3: Type the required text into the Text Object. Select Height - Expand to fit
Step 5: Select the text which is dynamically placed at Run time and make it into floating field by selecting Insert - Floating Field.
Step 6: Map the Floating field, Which is placed in the Subform where the Text object is wrapped, with the Interface Global Variable ( Or any other Field as required ).
Step 7: Select the Floating field and Change the style to bold.
That's it...
Please let me know if nay additional details required.
Please Reward if Useful.
Regards,
Sivanand Ala
