Hello World – 3

Don’t worry ! This is the last; and important.

Extract DEFINE LABEL – END LABEL structure or @ …,… LABEL command ( which one is currently exist) and then instead of them place this line :

MsgBox( "Hello World !" )

In HMG, there are a lot of message functions, with name prefixed by “Msg“; for details please look at HMG Message Functions page.

After building and running, try a more important feature: reduce your program to these minimum size:

#include <hmg.ch>
PROCEDURE Main
   MsgBox( "Hello World !" )

RETURN // Main()

In fact, as a rule, every HMG project must have one and only one “Main” window. This message functions are exception of this rule. If you have only message function(s) you can build a program without main window.
