Split-Screen Mode

In split-screen mode, you can use one half of the screen for editing an object (editing section) and at the same time have another Natural object displayed in the other half (display section). In addition, you can copy the definitions shown in the display section.

The following types of Natural object can be displayed in split-screen mode:

DDMs (Data Definition Modules), data areas, programs, subprograms, subroutines, helproutines, copycodes, texts, maps, classes, functions and Predict program descriptions.

The instructions below show how to display the definitions of another Natural object and copy them into the object you are currently editing.

Start of instruction setTo display and copy definitions with SPLIT

  1. In the current source, enter the SPLIT editor command (described in Editor Commands) to display the source of the object from which you want to copy text, for example:

    SPLIT P LDATEST1

    Split-screen mode is set with the current source (in the example below program PGMTEST1) in the editing section (upper half) and a local data area (LDATEST1) in the display section (lower half) of the editor screen as shown in the example below:

       >> -----------Columns 001 072  <<  Program PGMTEST1 Lines  187    User SAG

       001730    then

    Notes:

    1. Because it is not possible to modify the definitions in the display section, not all editor commands are available. PF keys are reserved for the editing section. Thus, commands meant for the display section must be issued using the command line.
    2. The SWAP editor command can be used to move the cursor between the command lines of the display and editing sections.
  2. In the display section, mark the block of lines to be copied from LDATEST1, for example, by entering the line command CC next to the first and the last line of the required block.

  3. In the editing section of PGMTEST1, next to the line below which you want to place the block of lines, enter the line command A.

    The marked block of lines is copied into PGMTEST1 below the line where you entered the line command.

  4. If required, terminate split-screen mode by entering the SPLIT END editor command.
