Read Only Buffers On compilation

[flebber]

I seem to have an odd behaviour when executing scripts in emacs. The
scripts work fine if no input is required. But when input is required
the compilation buffer is read-only. How can I make the buffer read-
write so that input can be taken. So for example a very basic script
asking for input such as below would work in emacs.

puts "What Directory do you want"
STDOUT.flush
file = gets.chomp
Dir.foreach("C:/"[file])  do |entry|
  puts entry
end
