This function creates an instance of the Web Service Client:
fgl_ws_create("handle", "service name", "port name", "operation")
This instance is then referred to in the 4GL code by its handle and can be called any number of times while that handle is still open. It can be executed, have its input parameters changed, have its output values checked, and have its error information checked any number of times whilst still open. This function will return a TRUE value if the instance was created successfully and a FALSE value if it fails to create an instance:
CALL fgl_ws_create("myAdd", "Web_Service_Simple", "Simple", "add")
The handle can be an arbitrary value, but must remain consistent throughout the 4GL Web service call.
