Bold in Report paragraph body

Question

This solution is for Oracle Report.
I create a letter where one part of the paragraph (v_meas)needs to be in bold only if the variable v_meas is not null. Below is my code for this paragraph.
Please, some body can tell me what I need to use.
Product Information:
Oracle9i Enterprise Edition Release 9.2.0.4.0 - 64bit Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.4.0 - Production
if(v_meas is null) then
v_body := '§ 10-33.02 - Community Small Business Enterprise Program Measure: ________' || CHR(10);
else
v_body := '§ 10-33.02 - Community Small Business Enterprise Program Measure: ' ||v_meas||CHR(10);
end if;

Answer 1

What I need to create is no label because the example that you give me are all fields.
Below is what I try to do in my report that create a letter (Oracle Report 9i)
I created a "Formula Column" for a paragraph in my letter and the ones that need to be on bold are ":advertised_date" field and the information after the word "Section:".
