Line separators in Creator API

I have a problem using the new Zoho Creator API.
I am trying to use the RPC CSV API to view data.
According to the documentation, you use a form hidden field to send the request to filter the data. This request have to be separated by "line separators" as it is said in the API docs (I guess you mean line feeds or carriage returns).
The problem is: I separate the data with the ''enter" key, but this is not recognized by the Zoho page that receives the data, and this page sends an error message saying that the name of the application is incorrect. I assume that the reason for this error message is that the data is not formatted with the "line separator" anf therefore is nor reading ths CSV String correctly.
Help Please.
