Navigating in Natural

Command	Brief Description
`FIN`	Terminates a Natural session.
`LAST`	Displays the system commands that were last executed, and allows you to execute them again.
`LOGOFF`	Causes the library ID to be set to `SYSTEM` and the Adabas password to be set to blanks. The contents of the source program work area are not affected by this command.
`LOGON`	Establishes a library ID for the user. In the specified library, all source or object programs saved during the session will be stored (unless you explicitly specify another library ID in a `SAVE`, `CATALOG` or `STOW` command).

Managing Applications with Natural Objects

Command	Brief Description
`CATALL`	Catalogs (compiles) all objects or selected objects in the current library.
`CATALOG`	Catalogs (compiles) the source code currently in the editor work area, and if the syntax has been found to be correct, stores the resulting cataloged object in the Natural system file.

`LIST`	Lists one or more objects contained in the current library or the contents of the editor work area.
`READ`	Transfers a source object from the Natural system file to the editor work area.
`RENAME`	Changes the name of an object or the name and the type of an object.
`RENUMBER`	Renumbers the source code currently in the editor work area.
`ROUTINES`	Shows you which objects in the current library use which external subroutines.
`RUN`	Compiles and executes the source program currently in the work area of the editor.
`SAVE`	Stores the source code currently in the editor work area as a source object in the Natural system file.
`SCAN`	Searches for a character string within a source with the option to replace the string.
`STOW`	Catalogs (compiles) and stores source code as both a source object and a cataloged object in the current Natural system file.
`STRUCT`	Performs structural indentation of a program source and helps detecting structural inconsistencies.
`SYSDDM`	Creates and maintains Natural data definition modules (DDMs).
`SYSERR`	Creates and maintains the messages you wish your Natural applications to display to the users.
`SYSMAIN`	Transfers Natural objects within the Natural system from one library to another.
`SYSNCP`	Creates and maintains the command processors to be used in your Natural applications.
`SYSOBJH`	Processes Natural and non-Natural objects for distribution in Natural environments.
`SYSRPC`	Invokes the SYSRPC utility to create and maintain remote procedure calls, that is, provides the settings necessary to execute a subprogram located on a remote server.
`UNLOCK`	Displays locked Natural objects with the option to unlock them.
`WHICH`	Lists objects in the libraries used at run time in the Library Search Order.
