Invoke orchestration through E1 Pages (sample)

HI,

I created orchestration, I know that we can invoke orchestration through B98ORCH. but I need some sample to invoke an orchestration through E1 page. I have seen latest tool release 9.2.6 have composed page to invoke orchestration. but we are in tool release of 9.2.5.3. I am trying to invoke through E1 page. please help us wit some sample to invoke orchestration where we can pass input (not array) during runtime to orchestration.
