I have resoled that problem. I have ruby working correctly, it turned out the problem was the PATHEXT somehow I had deleted everything but RB & RBW, so once that was fixed I was in good shape.
However being the inexperienced person that I am I have now moved on to a different problem. I will attach the text file that I am trying to read with the script and paste the script below. If you have time to look at it I would appreciate it. Basically it looks as if it recognizes the text file but does not read or display the contents.

my_path = "C:\\Ruby\\Text\\"

warnings  = 0
error = 0
 
d = Dir.new(my_path)

d.each do |fl|
   unless fl == '.' or fl == '..' then
 puts my_path + fl
  File.open(my_path + fl, "r").each do |line|
    if line =~ /ERROR/ then
      error += 1
    elsif line =~ /WARNING/ then
       warning += 1
    end
   end
   
  end
end
puts warning.to_s
puts error.to_s
