- 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 or
GUI/traditional 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.
