Teleprocessing Network Statements

Teleprocessing Network Statements

Three Types of Teleprocessing Network Statements

You use three system generation statements to define a teleprocessing network:

LINE defines a group of hardware devices (physical terminals) that use the same access method.
PTERM associates a physical terminal with a line and defines device characteristics. A physical terminal is any teleprocessing device or group of devices including printers, teletypes, and CRT terminals. A physical terminal can be associated with only one line.
LTERM associates a logical terminal with a physical terminal and defines the physical terminal as an interactive terminal, a printer, or a batch device.

Associating Logical and Physical Terminals and Lines

Logical terminal/physical terminal associations and physical terminal/line associations are established during system generation in one of two ways:

Explicitly by naming the associated physical terminal in the LTERM statement and by naming the line associated with the physical terminal in the PTERM statement
Implicitly by establishing currency with a LINE statement and coding PTERM statements for each physical terminal in the line, and by establishing currency with a PTERM statement and coding an LTERM statement for the associated logical terminal

This section presents:

Syntax and syntax rules for the LINE, PTERM, and LTERM statement parameters that apply to all device types. ADD/MODIFY/DELETE and DISPLAY/PUNCH syntax for each entity type are presented together. Syntax rules follow the presentation of both types of syntax. Rules presented in System Generation Compiler are not repeated.
Device-specific LINE and PTERM statement parameters.
