the proc is written in this way.

procedure header(wname varchar2) is
xheader varchar2(200);
xdate varchar2(30);
win_width number;
mco_name coname.name%type;
mcent2_name varchar2(100) := name_i('global.cent2_name');
mform_no uttmenu.form_no%type := name_in('global.form_no');
mprog_sl number := to_number(name_in('global.prog_sl'));
mno number := 0;
mprogs varchar2(30) := lower(name_in('global.progs'));
mowner varchar2(100);
mco_name := name_in('global.co_name');
g.co_code := name_in('global.co_code');
select to_char(sysdate,'dd-mon-yyyy') into xdate from dual;

xheader := initcap(rpad(mowner,70)) ||
initcap(rpad(mco_name,75)) || initcap(xdate);

set_window_property(wname,icon_name,name_in('global.ipath') || 'earth');
g.form_desc := ' ' || rpad(initcap(rtrim(mcent2_name)),50)
|| upper(mform_no);
when others then
g.dummy := g.cent(sqlerrm,1,1);
g.dummy := g.cent(error_text,1,1);
end header;
mno := 0;
select no into mno from appreqd where prog_sl = mprog_sl
and co_code = g.co_code;
when others then
mno := 0;
-- null;
if mno = 0 then
g.app := 0;
g.app := 1;
end if;
when others then
-- g.head2 := true;
g.dummy := g.cent(sqlerrm,1,1);

please explain the following wat they do.
1>g.header( ' main ' );
Above is the way how procedure is called. wat do they mean by 'main'?
2>mcent2_name varchar2(100) := name_in('global.cent2_name');
mform_no uttmenu.form_no%type := name_in('global.form_no');
mprog_sl number := to_number(name_in('global.prog_sl'));
mprogs varchar2(30) := lower(name_in('global.progs'));
why the name_in function is used.
3>xheader := initcap(rpad(mowner,70)) ||
initcap(rpad(mco_name,75)) || initcap(xdate);
how this works?
4>set_window_property(wname,icon_name,name_in('global.ipath') || 'earth');
wat do they mean by wname and wat does name_in('global.ipath') || 'earth' this do?
5>g.form_desc := ' ' || rpad(initcap(rtrim(mcent2_name)),50)
|| upper(mform_no);
how does this work?

Thanks in advance

I'm sorry, but your message is almost unreadable. The code is unformatted (not that the post itself misses [code] tags, but really IS unformatted) and I'm not in the mood to search what code belongs to what BEGIN-END or IF-THEN-ELSE block.

Also, part with your questions is written the same way - unreadable; I can't see what is the code and what are your own words.

Please, take some time and read the OraFAQ Forum Guide. It will show you how to properly ask a question, how to format it; use punctuation; don't be afraid to split your thoughts into paragraphs in order to improve readability.

Once you do that, I might look at it. In the meantime, you can hope that someone who is less picky than me will see your question and answer it.

My guesses,

1. 'main' is the window name passed to the procedure 'header'

2. Name_in - Returns the value of the indicated variable.
The returned value is in the form of a character string. Hence you can find to_number(name_in('global.prog_sl'));

3. select initcap ( sysdate) from dual will return 12-Mar-08.

initcap(rpad(mowner,70)) ||initcap(rpad(mco_name,75)) || initcap(xdate);

will return NULL since none of the variables are initialized.

4. wname is the Window Name

5. Concatenating two variables, cent2name and form number to give the form a suitable name
