Description

Procedure ShowMessage (const Msg: string);
The simplest message dialog: takes a simple string as argument,
displays it in a stereotyped box,
and waits for a mouse-click or enter-key event
before returning to the calling routine or program.

This is a modal procedure call,
that is the box is displayed, receives focus,
and does not relinquish focus until the OK box is clicked or otherwise selected.
