Hi:
This is one of those "it depends" answers.
First, "bigger" can mean wider (a longer line than the other lines), bigger font size or higher (taller line than the other lines). And, second, it depends on what destination you're talking about.
Generally, if you are talking about LISTING destination or the Output Window, the answer is NO -- with PROC PRINT and NO with PROC REPORT except at a break point using a LINE statement -- and yes with DATA step to FILE PRINT. If you are talking about ODS destinations, such as HTML, RTF or PDF, the answer is MAYBE. ...And that really depends on what you mean by bigger.
If you mean you want the report row for Observation 5 to extend -outside- the boundary of the report table (wider) that is not possible because your whole report is in a TABLE and one row in the table cannot be WIDER than the whole table -- for ODS destinations like RTF, PDF and HTML. This is where DATA step to LISTING with PUT statements could let you construct lines however you wanted -- but that kind of "free-format" output is really only available in listing. But, if you want the font_size for the Observation 5 row to be bigger in ODS HTML, RTF and PDF, you can do that -- with PROC REPORT (not PRINT). (And of course, everything is pretty much one font size in the LISTING window -- so that's a NO for LISTING).
Consider this example for making the font size of observation 5 bigger:
[pre]
ods html file='c:\temp\big5.html ' style=sasweb;
ods rtf file='c:\temp\big5.rtf' style=sasweb;
ods pdf file='c:\temp\big5.pdf' style=sasweb;
proc report data=sashelp.class nowd;
column name age height;
define name / display;
define age /display;
define height / display;
compute name;
obsno + 1;
if obsno = 5 then do;
call define (_ROW_,'style',
'style={font_size=16pt font_weight=bold}');
end;
endcomp;
run;
ods _all_ close;
[/pre]
Making the cell height higher is also possible -- at least for HTML and RTF by changing the CALL DEFINE statement (Note that each destination uses a different unit of measure):
HTML:
[pre]
call define(_ROW_,'style',
'style={cellheight=50px vjust=m}');
[/pre]
RTF:
[pre]
call define(_ROW_,'style',
'style={cellheight=.85in vjust=m}');
[/pre]
I found that I could not make cellheight in PDF higher in the middle of a table using the cellheight attribute. I don't know if this is an Adobe limitation or not. You could insert some ODS ESCAPECHAR line feeds into the NAME value in PDF in order to make the whole row higher. And, there are alternate methods in HTML to make font and other changes, using CSS style selectors (as opposed to ODS style= overrides, that are shown above).
In addition, with PROC REPORT, you could also pre-process the data and make a "dummy" break variable that occurred just on observation #5 -- but entails a bit more data step processing.
As you see, the answer really does depend on your destination and what you mean by wider. For more help with this question, your best bet is to contact Tech Support, as they can assess your report requirements and determine what your destination of interest is and help you come up with the best technique to achieve what you want to achieve.
