How to use Input and Output variables on a Script Node

Configuring the Script Nodes to use Input/Output variables 

In a Kofax TotalAgility business process, we have two string variables (any type can be used, this is for an example only)
NameIn
NameOut

Add your desired type of Script node to the process,
Map the variables as inputs/outputs depending on your requirements
i.e. 
When getting the value of a process variable in a script, assign the variable as an input to the activity.
When setting a the value of a process variable in a script, assign the variable as an output from the activity

Script Node example 

dim sNamevalue
dim sNameValueOut

sNamevalue= Sparms.Find("[NameIn]")
sNameValueOut = UCase(sNamevalue)
SParms.SetOutputParameter"[NameOut]", sNameValueOut

C# Node example 

using System; 
using Agility.Server.Scripting.ScriptAssembly;

namespace MyNamespace
{ 
 public class Class1
 {
  public Class1() 
  {
  }
  [StartMethodAttribute()] 
  public void Method1(ScriptParameters sp) 
  {
    //            
    // TODO: Add start method code here
    //
   string Name = sp.InputVariables["[NameIn]"].ToString();
    sp.OutputVariables["[NameOut]"] = "any value";
  }
 }
}

VB.Net Node example

Imports System
Imports Agility.Server.Scripting.ScriptAssembly
Namespace MyNamespace

    Public Class Class1
            <StartMethodAttribute()> Public Sub Method1(ByVal sp As ScriptParameters)
            '            
            ' TODO: Add start method code here
            '
        Dim Name
           Name = sp.InputVariables("[NameIn]")
           sp.OutputVariables("[NameOut]") = "value"
            End Sub
    End Class
End Namespace
