This is not Oracle forms where in we call paramlist and assign it to call_form.. its oracl EBS where in we dont use call_form but we use fnd_funciton.execute function to call in other form.
This being the case, I recommend you ask your question in the EBS General Discussions forum to ask your question. The EBS framework has methods for setting Profile values (if I remember correctly) that you use when passing values between forms. I don't recommend you use Globals in this instance since the EBS has a standardized way of handling this. This also makes your Form compliant with EBS development standards.
