Edit-Mode Windows

You can interactively develop and execute a SeeView program from a window that is in

edit mode on the Help page. This virtual window interface to the SeeView interpreter

provides a simple way to develop and debug SeeView programs.

The following steps load the current shell into a special window labeled SeeView on

the Help page. Once you load a program into the SeeView window, you can debug it.

You can use the Seedit GET command to load any program or script file into the

SeeView window.

To set up the Help page for interactive debugging:

1. Press F11.

Once the Help page appears, press F11 a second time. A window editor labeled

SeeView is automatically created in the largest free window on the Help page.

Breaking up this window into a larger SeeView window and a smaller free window

below it provides a convenient means of displaying syntax errors and user variable

values.

2. Load the SeeView command files into the SeeView window on the Help page by

using the Seedit GET command.

3. Enable edit mode for the SeeView window by pressing Insert-Line or F5 when the

cursor is on the sill of this window.

4. Once the editor is enabled, press SF15 when the cursor is in this window to

execute all statements contained in the cache for this window.

If the program causes another page to appear, you can return to the Help page by

pressing F11.

Specifying a section through the ALTER SHELL file [ ( section-name) ] statement

restricts SF15 execution to a specific ?SECTION section-name within the target

shell.

Figure 7-1 on page 7-3 shows an example of a program contained in a window on the

Help page. This program displays a menu of utility names that you can use to start the

utilities on selected pages of the terminal.

The window below the SeeView window is a free window that you can use to display

syntax errors, variable values (PRINT statement), and execution traces (ALTER

STMTTRACE ON).
