I ran the following sample from Powershell Quick Reference, but I got error.
Can you tell why?

POSH >Get-Process |foreach {BEGIN{$x=1}
>> PROCESS{$X++}
>> END{"$X Processes"}}
>>
ForEach-Object : The script block cannot be invoked because it contains more
than one clause. The Invoke() method can o
nly be used on script blocks containing a single clause.
At line:1 char:21
+ Get-Process |foreach <<<< {BEGIN{$x=1}

Yeah, the documentation certainly can be improved. I think they ment

Get-Process | &{BEGIN{$x=1} PROCESS{$X++} END{"$X Processes"}}

Begin, Process, End are parameters on the Foreach-Object cmdlet. So you can
be explicit like so:

Get-Process | foreach -BEGIN{$x=1} -PROCESS{$X++} -END{"$X Processes"}

or you can rely on positional parameters:

Get-Process | foreach {$x=1} {$X++} {"$X Processes"}

All of your solutions work. The documentation is also wrong to start array
count with $x=1, it should be $x=0.

Thanks for your help.
