Expanding variables

[Matteo Riva]

If I have these lines in a script:

let filename = something
new filename

new takes the literal string 'filename' instead of expanding it and
using its value. How can I tell :new to expand the variable instead?

Thanks

Hi Matteo!

It's because :new is an ex command and expects a filename and not an
expression. Therefore you have to use exe to evaluate an expression.
:exe ":new " . filename

Christian

You can use exec:

:exec 'new '.filename
