<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">i have downloaded data from postgresql into a file my haskell program.<br>
i can of course edit this file with say vim.<br>
<br>
can i run vim on that file from within haskell and after quiting vim<br>
have control returned to my haskell program?<br>
<br>
the situation is like calling vim to edit my claws-mail emails instead<br>
of using the native editor. after editing, i quit the external editor<br>
and am returned to the native editor.<br>
