Okay sounds good. I tried this creating an .htm document. I was wondering if there is a page to read & write my .htm document and then have browser automatically read and execute the file I wrote. Basically have the browser open the file that my program just wrote.

It’s even better if you pass a block to File.open, like I show below. The advantage of this is that you do not need to close the file explicitly - File.open will open the file, execute the code in the block, and then automatically close the file - even when an exception occurs. So it’s more convenient and more safe, because you won’t have a resource leak in case an exception occurs:

File.open(my_file, ‘r’) do |f|
file_data = f.read
end
