\dDATA\
  Includes inline data in the string. The data is not displayed, but
  can be read by class codes, or used in level titles to provide data
  and delimieters for the auto-generated table of contents. Data items
  are separated by semicolons; each item can be a underscore to mean a

\iCLASS:NUMBER\
  Displays a picture. Give the class name (without $ at first) and a
  colon and the zero-based index number of the picture in that class.
  This is then followed by another backslash. The picture may span
  multiple lines; it will automatically move the text to make room.

  the object cannot be created due to the CollisionLayers, or if the new
  object is destroyed before its CREATE message returns.

cz?  ( any -- bool )
  True if the value is a class or zero, or false if it is neither a class
  nor zero. Error if it is a sound.

Data  ( string index -- ... )
  Read string data. If the index is a number, it is the zero-based number
  of which data block in the string to read; all of the data in that block
  is pushed to the stack. If there isn't enough data blocks, then nothing
  will be pushed to the stack. If the index is the KEY message, then all
  of the key codes of the quiz buttons in the string are push to stack.

DelInventory  ( class image -- ) **
  Delete an item from the inventory; see SetInventory for more details.

Delta  ( in1 in2 -- out )
  Subtracts the smaller input from the larger (unsigned).
