Poll

Poll() as Boolean

Checks to see if a replies have been received from a deferred synchronous Start or Send request. Possible values are:
True
No further replies outstanding
False
Further replies outstanding

A CICS® server transaction may send more than one reply in response to a Terminal.Start or Terminal.Send call. More than one Terminal.Poll call may therefore be needed to collect all the replies. The return code indicates whether you need to perform more poll requests.
