Question about documentation and embedded blanks

I can't seem to find the documentation that provides an answer to the relatively simple problem
below. Where should I look?

---------------------------
Below is a brief excerpt from a PS script. When I pass a path with embedded blanks I receive an
error on the "get-item" line.

param($file1=$(throw "param file1 required"), $file2=$(throw "param file2
required"))

## both files must exist
$f1 = get-item $file1

---------------------------

Regards,

Frank

The "get-item" line is not the root problem. I use a command line like:

>powershell "& '%script%\myscript.ps1' file1 file2"

The problem occurs when file1 or file2 contains spaces.
