How to execute file I'm editing in Vi(m)

Question

How to execute file that I\'m editing in Vi(m) and get output in split window (like in SciTE)?

Of course I could execute it like that:

:!scriptname
<

Based on @SethKriticos and @Cyril answers I now use the following:

function! Setup_ExecNDisplay()
  execute "w"
  execute "silent !chmod +x %:p"
  let n=expand('%:t')
  execute "silent !%:p 2>&1 | tee ~/.vim/output_".n
  " I prefer vsplit
  "execute "split ~/.vim/output_".n
  execute "vsplit ~/.vim/output_".n
  execute "redraw!"
  set autoread
endfunction

function! ExecNDisplay()
  execute "w"
  let n=expand('%:t')
  execute "silent !%:p 2>&1 | tee ~/.vim/output_".n
  " I use set autoread
  "execute "1 . 'wincmd e'"
endfunction

:nmap  :call Setup_ExecNDisplay()
:nmap  :call ExecNDisplay()

Use F9 to setup the new window and F2 to execute your script and tee to your output file.

I also added the script name to the output file name, so that you can use this for multiple scripts at the same time.
