If all the OP wants is a Presence test on a small number of possibilities,
a simple loop seems appropriate. If high speed is required (seems
unlikely for this application...), a Boolean lookup array
type Phone_Numbers is range 1000 .. 9999;
Is_Present : constant array(Phone_Numbers) of Boolean
:= (1795 | 2006 | 2007 | 2012 | 2013 | 2014 => True,
others=>False);
would do the job.
