Usage
The MESSAGE instruction
displays a message to the user in an interactive program.
The message will remain visible to the end user until the next MESSAGE
instruction.
To cleanup the message text, use MESSAGE "" .
In TUI mode, the text is displayed in the message line of the current window. The message line
can be defined by the OPTIONS MESSAGE
LINE instruction. Note that the default message line position is the same as the
MENU option comment line.
In GUI mode, you can use the STYLE attribute to
reference a style
definition. This allows you to display errors or messages in GUI mode with more sophisticated
visual effects as the regular TTY attributes. If you want to apply a style automatically to all
program messages displayed with the MESSAGE instruction, you can use the :message pseudo selector in the
style definition.
Example
INPUT BY NAME custrec.* ...
BEFORE INPUT
MESSAGE "Enter customer data."
