How to manipulate output parameter

Question

Hi folks, 
 We are using Identity Manager 8.0.1. 
 I have a process orchestration which involves process steps of ScriptComponent --> MailComponent - SendRichMail --> MailComponent - SendRichMail. I would like to get the output of the scriptcomponent and manipulate it (i.e. split the string) and pass one half to one mailcomponent and the other one to the other mailcomponent. 
 How we have configured so far are as follows: 
 The ParamOut for ScriptComponent is a fixed length string. 
 On the MailComponent process step, which one sits on top of the 2nd mailcomponent, we set a ParamName1 and ParamValue1 on both components to take in the return String of the ScriptComponent. 
 By setting Value = "&OUT(returnString)&" , we are able to get the full String, but we want to only some characters. 
 So, I tried something like Value ="&OUT(returnString)&".toString().SubString(0,4) but it will give me the literal string. 
 On the other hand, I've tried to return an array String in the ScriptComponent so that both MailComponents are able to access by "&OUT(returnString)&"[0] and "&OUT(returnString)&"[1] respectively, but the results turn out to be the same as the previous. 
 Appreciate and seeking suggestions on how we should go about to do this. 
 Thank you !

If you take a look at the documentation here https://support.oneidentity.com/technical-documents/identity-manager/8.0.1/configuration-guide/94 you will find that in your use case, you do not need to set the process step parameters ParamName1(-n) and ParamValue1(-n) as you can control the parameter name explicitly in your parameter collection while generating the process. 
 So in your code, you are setting the parameter MyParam with htParameter .Add("MyParam",<myvalue>) 
 In the rich mail template, you can reference the parameter than with $PC(MyParam)$ 
 That should do the trick.
