Vimscript: outputting into a new (split) window

From within Vimscript, how does one open a new开发者_如何学Go split window and insert the contents of a variable?

I'm trying to write a script that applies a function to the current buffer and displays the result in a split window.

Thanks.

To open a new window, use :split. To insert the contents of a variable, use :call append(0, g:some_var)

I never used vimscript (excluding simple keyboard mappings and settings), but here are some links that might help:
