Although this is a layered graphic, it cannot be edited using the Idea Studio. It is for use within text mode editing only. Will not display tab characters.

Examples:

ZText(100, 100 { Lower left corner of text },
      "Hello World" { Text to display }, 
      2 { Text is green}, 
      0 { Use default font }); 

This places the string "Hello World" on the screen at (100, 100) with white text in the system font.

ZText(500, 100 { X, Y coordinates },
       Format(0, 2, DeadBand(pressure, 5)) { Displayed value }, 
       0, 0); 

This displays the value of variable, "pressure" on the screen. However, the display is only updated when pressure changes by more than 5 (higher or lower) from the last update.
