How To Permanently Add-to a Users PATH Statement in the Bash Shell

["Stephen P. Molnar" <s.molnar@sbcglobal.net>]

The Subject line is the problem with my Debian Buster platform. Now from 
Google I see that there has been a change in the way Debian handles this 
problem.

My user path statement is:

comp@AbNormal:~$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

Now I have a number of applications that have multiple executable in the 
app /bin subdirectory. Hence the need to add to the users PATH statement

As an example I have:

/home/comp/Apps/ADFRsuite-1.0/bin

which I would like to add to the PATH statement and:

export PATH=$PATH:'/home/comp/Apps/ADFRsuite-1.0/bin'

This works unless I open a new Terminal, in which case it is no longer 
in the PATH.

How do I make the addition persistent?

Thanks in advance.
