Application Design Considerations

The TCP/IP socket program interface is available only to CA IDMS/DC applications running under a central version. A batch program trying to use the interface receives a socket return code of RNOSLIND.

Server tasks started by a generic listener cannot do any terminal I/O such as #LINEIN, #LINEOUT, #TREQ and so on. If written in CA ADS, they should be mapless dialogs.
