Tip #1388: Vim and ocaml interpreter

I try to learn ocaml, and I add this lines in my .vimrc to run the code in the ocaml interpreter :

set sb
map <f11> :split /tmp/ocaml \| %d \|setlocal ft=omlet \| setlocal autowrite \| r!ocaml < # <CR>
map <f12> :dr /tmp/ocaml \| %d \|setlocal ft=omlet \|setlocal autowrite \| r!ocaml < # <CR>

--
the first map <f11> , open a temp file in a split  and write the output in it (with omlet syntax)

I use the second (<f12>) to do it if I have allready a split with the result.

Soif you know a better way to do the same things please write it :D

I do a set autowrite.. but I am sure we can use the same property of :he command (a buffer in read only without needing to save it)

please comment
thx
