Compatibility with Other TPF Releases

In order to maintain functional and operational compatibility with prior TPF releases, special considerations have been given to the use of existing applications (for example, airlines reservation) from terminals such a the 2915, 4505 and 1977. For this purpose, all application programs whose input message editor is UII (03-UII) are indicated in each RCAT as a RES-type application. When an agent on a terminal wants to access a RES-type application, he must first request log-in to the application, followed by a sign message. Because of the special considerations given to the RES-type applications, many MR components contain certain code used to process input from terminals connected to RES-type applications. For example, the Agent Assembly Area (AAA) record is retrieved by WGR rather than the Routing Control Block (RCB), messages are input to RES-type applications in IMG format (IMG), no RCPL is initialized, and so on.
