[Tutor] Using Python with VI

[Barry Smithers]

Hello everyone.

I'm having difficulty with a program call from inside of VI.  What I
basically need to do is get the line numbers input in the ex command.  Or
maybe even get the text on those lines to go into a list.  For example the
ex command ":20,21!xxx.py" would run xxx.py as a whole, but I need the data
currently on lines 20 and 21 for modification.

Can anyone help??

Cheers

Barry
