In contrast with the workstation administration client, when you use the the ISPF administration interface, you are operating directly on the target CICS control file. This means that new or modified objects are saved immediately in the target CICS control file when you use the ISPF administration interface save function to save an object. In the case of the workstation administration client, you operate on a downloaded copy of an object and when you save your changes you are saving only a local copy, and the target CICS control file is not updated until you upload the object to the CICS region control file on the host through the communication server.
