When executing a script with SQL PLus, I was prompted to enter value for lt, gt, and apos.

Here are some code examples in this script.

v_qry := replace(v_qry, '&lt;', '<');
v_qry := replace(v_qry, '&gt;', '>');
v_qry := replace(v_qry, '&apos;', '''') ;

How to execute this script without being prompted to enter values?

Thank you Frank
