Use of #BYVAL(variable-name)

How to customize our title display??? How do we insert a text in the title???

This option #byval helps the user insert text at the position it is placed in the title statement.

For example in the code below:

The use of #byval option with the variable TRTGRP in the BY statement (within a proc step) makes its dynamic value get displayed in the title. As result of which we get different treatment groups displayed in the title part.

title1 "Listing of Patient Population";
title2 "Treatment Group=#byval(trtgrp)";
proc report data=dummy nowd headline headskip spacing=1 missing;
by trtgrp;
column(subj rand saft ittp eval);

define subj/ order_ width = 20 left spacing = 0 "Subject" ;
define rand/ order_ width = 20 center "Randomized";
define saft/ display width = 20 center "Safety" ;
define ittp/ display width = 20 center "ITT";
define eval/ display width = 20 center "Evaluable";

break after subj / skip;
run;
