SCREEN section

The SCREEN section defines the form layout for TUI mode forms.

Syntax

SCREEN [ SIZE lines [ BY chars ] ] [ TITLE "title" ]
{
  { text | [ item-tag [ | item-tag ] [...] ] }
  [...]
}
[END]

lines is the number of characters the form can display vertically. The default is 24.
chars is the number of characters the form can display horizontally. The default is the maximum number of characters in any line of the screen definition.
title is the title for the top window.
item-tag and text define form elements in the layout.

Usage

The SCREEN section must be used to design TUI mode screens. For a GUI mode application, use a LAYOUT or STACKED LAYOUT section instead.

The SCREEN section must appear in the sequence described in form file structure.

This section is mandatory, unless you use a LAYOUT section.

The END keyword is optional.

Inside the SCREEN section, you can define the position of text labels and form fields in the area delimited by the {} curly braces.

Horizontal lines can be specified with a set of dash characters.

Avoid Tab characters (ASCII 9) inside the curly-brace delimited area. If used, Tab characters will be replaced by 8 blanks by fglform.

Example

SCREEN
{
  CustId : [f001   ] Name: [f002                ]
  Address: [f003                                ]
           [f003                                ]
