Natural supports two programming modes:
Structured Mode
Structured mode is intended for complex applications with a
clear and well-defined program structure. It is recommended to use structured
mode exclusively.
Reporting Mode
Reporting mode is useful only for the creation of ad hoc reports
and small programs which do not involve complex data and/or programming
constructs.
For more information on the differences between reporting and structured mode, see Natural Programming Modes in the Programming Guide.
To switch to another mode
Select the menu and press
ENTER. In the resulting Direct Command window
enter the system command GLOBALS as
described below and press ENTER.
To switch from reporting mode to structured mode:
GLOBALS SM=ON
To switch from structured mode to reporting mode:
