Use format!

pawn Код:

new string [ 128 ];

format( string, sizeof ( string ), "(ADMIN) %s says %s", user, message );
SendClientMessageToAll ( -1, string );

%s is a string, this is a combination of characters and numbers.

The first %s turns into whatever "user" is defined to, and the second %s turns into the message inputted.
