This section describes the RJESV command, which starts the Exchange/RJE line server,

and the system procedure calls that an application program can use to communicate

with the line server. Not all procedures that can be used are included; only those

procedures that are most commonly used and have considerations specific to their use

with Exchange/RJE are described here. These descriptions focus on how the

procedures are used with Exchange/RJE. For examples of how the procedures are

used with Exchange/RJE, see Appendix D. For a complete, general description of

every system procedure, see the Guardian Procedure Calls Reference Manual.

Only 16-bit I/O procedures are described here. However, all remarks also apply to

extended 32-bit I/O operations. For information on the differences between 16-bit and

32-bit I/O operations, see the Guardian Procedure Calls Reference Manual.
