I use Borland 5.5 to make console programs and is there any code that will make my output appear in a larger font ? (Ex: "Hello World " occupies the whole screen ? )
You can draw on the console window though, and accomplish much the same effect. See the following link for an example of how to access and draw on the console window's DC. http://www.daniweb.com/code/snippet217.html
Just use one of the text GDI routines to draw the text you want on the console window.
