Thanks a lot, Park and Sean.

Two questions:

- Sean, what do you mean by CG when you write in your message "This is exactly the type of error that CG causes"?

- Is there a set limit on the number of files that can be open? If so, how many?

- Park, you write that one option is this:

       inserta = File.new("./input/intro_subtemplate.txt").read

       should be

       f = File.new("./input/intro_subtemplate.txt")
       inserta = f.read
       f.close

  but, these statements seem logically (to this newbie) to be logically equivalent. Does the one-line method I used create a phantom file that can't be closed?

Thanks again!

-Kurt

correctly inserts the contents of file "intro_subtemplate.txt" into a
template file during each iteration, resulting in the creation of some 189
identical but differently named files in directory "./output". (There are

These error messages caused by too many open files.

Following three lines should be placed before IO.foeach loop.

inserta = File.new("./input/intro_subtemplate.txt").read
insertb = File.new("./input/install_unix_subtemplate.txt").read
insertc = File.new("./input/files_changed_sp_num-1_subtemplate.txt").read

Or

inserta = File.new("./input/intro_subtemplate.txt").read

should be

f = File.new("./input/intro_subtemplate.txt")
inserta = f.read
f.close
