You might also consider the flip-flop operator (see Flipin good, or a total flop?)

In your problem, the code would look something like:

while(<WORDLIST>)
{
    if( /^process/ .. /end process/ )
    {
        #recognize and skip first delimiter
        next if /^process/;
        #recognize and skip end delimiter
        next if /end process/;
        # do something with the middle.
        print;
    }
}

This does have the advantage that it restarts if you hit another line starting with process. Obviously, you can also do something special with the start and end points.

Of course, if you don't need to know when the data starts and stops, you could just do

while(<WORDLIST>)
{
    next if /^process/ or /^end process/;
    print;
}
