PeekCt™ 2.0 Guide
  The PeekCt FCMD supports a control that displays the current stack space, total free heap memory, and the largest block of contiguous free heap memory.

Operation
  The parameter displayed is determined by the control's VarCode which can be set manually in the control dialog or interactively by clicking in the control.  The VarCode values currently supported are:
  1 = show stack space
  2 = show free heap memory
  3 = show largest contiguous free heap memory
  4 = continuously shuffle blocks in heap
For proper operation, the Idle and Hook items should be set in the Messages Sent menu.  No use is made of the control's values, and no support is provided for resource or data linking.

Limitations
  No support for right or center justification.  No support for colors beyond frame, body, & content.  No support for hand scrolling.

Source Code
  The source code and development projects for this driver can be obtained as part of the Inside FaceWare 2.0 package.  It is an excellent example of a small, but useful ViewIt control driver.
