%let condition=( 1.2&gt;=1 and 1.2&lt;1.5 ) and ( 1123.1&gt;=800 and 1123.1&lt;1200 );<br>
<br>
&nbsp;&nbsp;  %if &amp;condition %then %do;<br>
&nbsp;&nbsp;&nbsp;  %put Y;<br>
&nbsp;&nbsp;  %end;<br>
&nbsp;&nbsp;  %else %do;<br>
%put N;<br>
&nbsp;&nbsp;  %end;<br>
<br>
%let condition=( 1.2&gt;=1 and 1.2&lt;1.5 ) and ( 1123&gt;=800 and 1123&lt;1200 );<br>
