Yep, you definitely need to RTM (Read The Manual).

First off, the function you're looking for is lowcase.  Second, the
expression

if Variable="lowcase(&con.)" then do;

resolves to

if Variable="lowcase(Cat)" then do;

which is not what you're trying to evaluate.  You need to put the quotes
around &con.
