Syntax

DISPLAY text AT line, column [ ATTRIBUTES ( display-attributes ) ]
  1. text is any expression to be evaluated and displayed at the given position in the current window.

Usage

The DISPLAY AT instruction evaluates a string expression and displays the result at a given line and column in the current window. This instruction is typically used in text user interface (TUI) text-based applications to display static text on the screen such as messages or decoration lines with - (dash) or _(underscore) characters.

Use of the DISPLAY AT instruction is recommended only in TUI mode. To display data at a given place in a graphical form, use form fields and the DISPLAY BY NAME or DISPLAY TO instructions, or use interactive instructions with the UNBUFFERED mode to automatically display program variable data to form fields.

When using DISPLAY AT in GUI mode, the text will only be displayed if the current window contains no form, or contains a form defined with the SCREEN layout.
