The editor command line is indicated by Command = = =>. In the command line, you can enter one of the following:
Any Natural system command.
For example: The system command CHECK can be
                              used for checking the syntax of source code and
                              SAVE
                              for saving source code (see also Saving and Cataloging
                                 Sources).
                     
For other system commands related to maintaining and using object sources, see Managing Applications with Natural Objects in the System Commands documentation.
An editor command (see Editor Commands and Editor Commands for Scrolling).
The name of a Natural program to be executed.
Additionally, the command line contains the following information (from left to right):
The programming mode: structured (Struct) or reporting
                              (Report) currently in effect. When a Natural object is read into
                              the source work area, the mode is set to the one which was in effect when the
                              object was saved (see also Saving
                                 and Cataloging Sources).
                     
For information on the differences between structured and reporting mode, see Purpose of Programming Modes in the Programming Guide.
To switch from reporting to structured mode or vice versa, enter an
                              S in the first position of Report or an
                              R in the first position of Struct and press
                              ENTER. 
                     
If you want to check whether structured mode has been activated or switch structured mode on, you can also set the programming mode for the current Natural session as described in Setting/Changing the Programming Mode in the Programming Guide.
