Parameters to script and back

Question

Hello 
 
 I can't find any information about how to send parameter values from a workflow to a powershell script and back (after modifying them). 
 What I already tried to pass parametervalues to a script: 
 $testvar = $Workflow.Parameter("test") 
 $testvar = $Request.Parameter("test") 
 To get values FROM the script BACK to the workflow parameters: 
 $Workflow.Parameter("test) = $testvar 
 $Request.Parameter("test") = $testvar 
 
 I'd be very thankful for clarifications! 
 Best regards

I don't think that this is an issue of parameterization, it is an issue of scope. 
 If you have a variable which is created at the Global scope, it will be accessible within any script module within that Workflow. 
 So, if I have a script module which assigns a variable with a global scope: 
 function setGlobal($request)
{

$global:var = "Set"

} 
 I can then access that variable in a different script module within the same Workflow by simply referencing the variable name and the scope: 
 function readGlobal($request)
{
$global:var | Out-File c:	emp\global.txt
} 
 
 This writes the word "Set" to a file, as expected.
