I am new to scripting all together and am trying to figure out how I can cycle through this variable so that the command can use the same variable to work. Any assistance would be appreciated.

&nbsp;

$server=‘dc2pa90048,tocpaIIB-TI,lsys7011a-TI’

pairdisplay -IM100 -g $server -fcx  
start-sleep -s 2

There are some great books for beginners, especially if you have no scripting experience.

Powershell is full of help files and there a ton of free videos, blogs, etc. available. The short answer is you need to look at [arrays](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_arrays?view=powershell-7) and [foreach loop](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_foreach?view=powershell-7). Another important item is [operators](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_operators?view=powershell-7), specifically call operators to call external non-Powershell commands.

```
$servers =' dc2pa90048','tocpaIIB-TI','lsys7011a-TI'

foreach ($server in $servers) {
    & pairdisplay -IM100 -g $server -fcx
    start-sleep -s 2
}
```

Please also re-read [Read Me Before Posting! You’ll be Glad You Did!](https://powershell.org/forums/topic/read-me-before-posting-youll-be-glad-you-did/) and ensure you use the PRE tags for your code.
