Mysterious parameters in job step

Question

Hello All, 
 I recently joined a project where we are, going to upgrade Q1IM from 6.1.2 to 7.1.2. 
 I was going through the custom process' and job queue and saw some steps having parameters magically appearing, though they were not present in the original process step. I am not able to understand from where these parameters are coming, so seeking help from you guys: 
 
 Parameters in the above step: 
 
 Below are the parameters of the step from the job queue: 
 
 I am not able to understand from where the extra parameters are coming? 
 FYI this is the second step of the process, first being the Event Catcher step, and their also nothing special is written in the generating condition or pre-script. 
 How can a step show parameters that are not present in the, process is driving me nuts... 
 
 Thanks

The OutValue_0 and OutValue_1 are return values that look like custom powershell objects, what is the process type of the process step?

Hi Dheeraj, 
 
As Paul said these 'mysterious' parameters are output values from previous job steps. Some components generate free/hidden output parameters such as the PowerShell component - this returns a parameter OutValue_0 which is an XML representation of the return value.
