Pascal Message Box Implementation: Custom Procedure Example

In Pascal, the 'msgbox' function is not available natively. However, you can create a custom procedure to display a message box-like dialog using the 'writeln' function. Here's an example:

program PascalMsgBox;

procedure MsgBox(message: string);
begin
  writeln('---------------------------');
  writeln('|                         |');
  writeln('|        Message Box      |');
  writeln('|                         |');
  writeln('---------------------------');
  writeln('|                         |');
  writeln('| ', message, ' |');
  writeln('|                         |');
  writeln('---------------------------');
end;

begin
  MsgBox('Hello, Pascal!');
end.

When you run this program, it will display a simple message box-like dialog with the provided message.
