working with strings

Could someone please explain why this happens like this

PS 1 > $a = "_string"
PS 2 > $a
_string
PS 3 > $b = "string $a_string"
PS 4 > $b
string

I would expect $b to be "string _string_string" as it does if I do
this

PS 8 > $b = "string" + $a + "_string"
PS 9 > $b
string_string_string

Thanks in advance

Andy

This is because _ could be part of the name of the variable

try this instead
PS> $a = "_string"
PS> $b = "string$($a)_string"
PS> $b
string_string_string

You could also avoid this by delimiting the variable with braces:

$a = "_string"
$b = "string ${a}_string"
