This command is used to invoke a Natural editor for the purpose of editing the source form of a Natural programming object.
Three different forms of command syntax exist. These are documented in the following sections.
Related command: READ.
See also Object Naming Conventions in the Using Natural documentation.
EDIT
[object-type]
[object-name
[library-id]]
|
The following object types can be edited:
|
|
|
CLASS
|
|
|
4 |
||||
COPYCODE |
||||
GLOBAL |
||||
HELPROUTINE |
||||
LOCAL |
||||
MAP |
||||
PARAMETER |
||||
PROGRAM |
||||
|
|
SUBPROGRAM |
|
||
N |
||||
SUBROUTINE |
||||
TEXT |
||||
VIEW
|
||||
7 (for
Function)
|
||||
Which editor is invoked depends on the type of object to be edited:
Local data areas, global data areas or parameter data areas are edited with the data area editor.
Maps are edited with the map editor.
Classes are edited with the program editor.
EDIT VIEW only works in the current library
and when an object-name is specified. If the object
to be viewed is a DDM, the DDM Services
are invoked.
All other types of objects - program, subprogram, subroutine,
7 (for function), helproutine,
copycode, text, description - are edited with the program
editor.
Note:
The text object "description" is available on mainframes
only. A description is a program description as stored and maintained in the
Predict Data Dictionary; an object of this type can only be edited if Predict
is installed.
The object types are described in the Programming Guide. The editors are described in the Editors documentation.
Note:
If you are in the program editor and enter
EDIT object-name (whereas
the Natural object is of type copycode, class, 7 (for function), helproutine,
program, subprogram,subroutine, text), a parallel edit session will be opened.
See also the description of the program editor command
NEXT.
If you specify the name of the object you wish to edit, you need not specify its object type.
With the EDIT command, you specify the name
of the object you wish to edit. The maximum length of the object name is 8
characters.
Note:
For DDMs, the maximum length is 32 characters.
Natural will then load the object into the edit work area of the
appropriate editor and set the object name for a subsequent
SAVE,
CATALOG,
STOW
command.
If you do not specify an object-name and there is no object in the source work area, the empty program editor screen will be invoked where you can create a program. If the source work area is not empty, the object will be loaded in the appropriate editor.
If the object you wish to edit is not contained in the library you are currently logged on to, you must specify the library-id of the library in which the object to be edited is contained.
If Natural Security is active, a library-id must not be specified, which means that you can only edit objects which are in your current library.

| object-type | object-name |
If you do not remember the name of the object you wish to edit, you can
use this form of the EDIT command to display a list
of objects, and then select from the list the desired object.
| EDIT * | displays a list of all objects in your current library. |
|---|---|
| EDIT object-type * | displays a list of all objects of that type in your current library. |
To select an object from a certain range of objects, you can use asterisk notation and wildcard notation for the object-name in the same manner as described for the system command .
EDIT
FUNCTION
subroutine-name |
The EDIT FUNCTION command may be used to edit
a subroutine using the subroutine name (not the object name) with maximally 32
characters.
Note:
Please note that the keyword FUNCTION used in this
syntax is not identical with the Natural object type 7 (for function) listed
above. See the description of object type
Function in the
Programming Guide.
Example:
DEFINE SUBROUTINE CHECK-PARAMETERS ... END-SUBROUTINE END
Assuming that the above subroutine has been saved under the object name
CHCKSUB, you may edit subroutine CHECK-PARAMETERS
either by issuing the command:
EDIT S CHKSUB
or by
EDIT F CHECK-PARAMETERS
