Oh, I see. Sorry, I misunderstood. You need to use the {left, top, right, bottom} coordinates. It shows under Example 2 in the Scripting Index for Text. Essentially what it does is create a box with lines at the specified coordinates which your text will be placed in. If you make the "right" coordinate too small it will cut off the text. As you make it larger, the box expands, which will start to move the text over as well. I'm not sure if there is an easy way to just specify top and left numbers without the others.
a="this is a \!nnewline \!nnewline \!nnewline";
Names Default To Here( 1 );
New Window( "Example",
Graph Box(
Text Color( "red" );
Text( Erased, {0, 50, 15, 20}, a );
)
);
