How to assign multiple lines string in Powershell Console

As per the section on maximum line length in The PowerShell Best Practices and Style Guide, I would suggest “splatting” the string, like this:

$myStr = ("The family of Dashwood had long been settled in Sussex. Their estate was " +
              "large, and their residence was at Norland Park, in the centre of their " +
              "property, where, for many generations, they had lived in so respectable " +
              "a manner as to engage the general good opinion of their surrounding " +
              "acquaintance.")

'@ should be first thing in the line or it is considered to be just a part of the string.

$test=@'
Test
Test
'@

This approach also works with @"/"@
