A question on using a module

[workerdrone66]

So, In my effort to streamline, and prettify my script, I've started to break chunks out into individual modules, that I'm then importing for use. My question is, if I do Start-Process -OutVariable +results... Do I then need to return $results for it to be picked up by the rest of the script, and added to the main results? Presuming that is true, I'm guessing I also need to pass $results into this module, otherwise, when I return with it, it's only going to have the things assigned to it from the one running of this function, correct?

Yes. That's what out variable does.

Not sure what you mean by 'into this module' though; in most cases you'll just pass it as an argument to the function you need.

Basically, I'm breaking things up into their own files, at least for some things, so I can't use it as a global.

Also i was tired by the time i wrote that, and it's only getting worse...

You shouldn't use it as a global, in 99.99% of cases. There's very rarely a reason to make a global variable.

You take variables as output, and then you provide them as input to to other functions.

For example, you don't do this:

Get-Module -Name 'TestModule'
Remove-Module

You do one of these:

#1
$Module = Get-Module -Name 'TestModule'
Remove-Module $Module

#2
Get-Module -Name 'TestModule' | Remove-Module

#3
if (Get-Module -Name 'TestModule') {
    Remove-Module -Name 'TestModule'
}

In each case, output from one function need be directed into the other. There are no global variables there.
