Vista - Creating objects with variable names in functions

Hi,

I am sure there is a better way but I would like to create objects with
names that are formed in a function that are accessable from the main PS
script. The names would be a variable concatenated with a parameter that is
passed from a for loop. Is this possible?

ie:

function setup1{
param([string]$script:num)
$scriptcproc${num} = new-object system.diagnostics.PerformanceCounter
}

# Setup objects

for ($i=1; $i -le 5; $i++){
setup1 $i
}

# Now work on objects that are now setup

for ($i=1; $i -le 5; $i++){
"Work on objects $prproc${num}"
}

You can use invoke expression in your function

PS > $c='$global:a=1'
PS > Invoke-Expression $c
PS > $a
1

You can create them like so:

Set-Variable "pcproc$num" <some value> -Scope Script

> # Now work on objects that are now setup
>
> for ($i=1; $i -le 5; $i++){
> "Work on objects $prproc${num}"
> }

Access it like so:

(Get-Variable "pcproc$num").Value
