This documentation contains information for operating Natural in a mainframe environment under various operating systems.

This documentation is organized under the following headings:

Configuring Natural | Describes how to link Natural objects to the Natural nucleus. Provides information on Natural user exits, Natural user access method for print and work files, Natural system files, Natural text modules, Natural configuration tables, and Natural storage management.
Profile Parameter Usage | Provides an overview of the hierarchical structure of the different levels on which Natural parameters can be set. Explains how values can be assigned to profile parameters statically, dynamically and at runtime. Describes how to build a Natural parameter module.

Describes the functions and the operation of the Authorized Services Manager (ASM). Explains the functions of the Natural Roll Server. Provides information on the Roll Server system requirements, operation, performance tuning and restart capability.
Natural in Batch Mode | Contains considerations that apply when running Natural in batch (Adabas data sets, sort data sets, subtasking session support for batch environments), and specifically when running Natural in batch mode under z/OS.
