Exchange/RJE Manual

About This Manual
104698 Tandem Computers Incorporated xv
This manual describes Exchange/RJE and how to use it. Exchange/RJE provides byte-
synchronous, batch-oriented communications between a Tandem NonStop system and
a variety of remote systems by emulating an IBM 2780 or 3780 Data Communications
Terminal. Three additional modes of operation, collectively called block mode, are
able to transfer records up to 4084 bytes long. Each block mode has specific
capabilities; all, however, are available through both the Exchange/RJE command
interpreter and the programmatic interface.
Audience This manual is written primarily for programmers and system analysts who design
and implement communications with remote systems using Exchange/RJE. Parts of
this manual provide information useful to system managers and operators who are H
Prerequisites This manual is written under the assumption that the reader is familiar with the
