ShowMessage Behaves Differently On Different Platforms
On desktop platforms, ShowMessage behaves synchronously. The call finishes only when the user closes the dialog box.
On mobile platforms, ShowMessage behaves asynchronously. The call finishes instantaneously, it does not wait for the user to close the dialog box.

Applications or the operating system itself use message windows to warn or inform the user. The title of the window is the project name. There is no option to click other than the OK button.

ShowMessage Behaves Differently On Different Platforms On desktop platforms, ShowMessage behaves synchronously. The call finishes only when the user closes the dialog box. On mobile platforms, ShowMessage behaves asynchronously. The call finishes instantaneously, it does not wait for the user to close the dialog box.


Example
TRObject Syntax

 var
   word : String;
 {
   word = 'Hello World';
   // Show a simple message
   ShowMessage(word);
   
   // Show a blank message
   ShowMessage('');
   
   // Split this into two lines
   ShowMessage('Hello '+#13#10+'World');
 }

Base Syntax

 var
   word : String;
 begin
   word := 'Hello World';
   // Show a simple message
   ShowMessage(word);
   
   // Show a blank message
   ShowMessage('');
   
   // Split this into two lines
   ShowMessage('Hello '+#13#10+'World');
