  main_canvas, main_block)
• c. set the splash window property
• window style dialog
• hide on exit true
• d. change the width and height properties for
  canvas and window to the same
• size
• e. change window titles
• f. create a new image item in splash_block
• set the size and x,y coordinates of the image
  item
• g. create a pre-form trigger to read in the
  splash image
• h. create a when-timer-expired trigger
• 2. Create main screen

• create a new menu from object navigator
• create menu items from menu editor (double
  click on the menu icon)

• for forms use the same trigger as the
  when-button-pressed trigger
• for reports/graphics use
• run_product(product,document,communication
  mode,
• execution mode,
  parameter list, display)
• communication mode
• asynchronous--the called product closes
  immediately after
• execution
• synchronous--the product has to be closed to
  return control
• execution mode
• batch--used for displaying a graph in a form
  item
• runtime--control transferred to reports or
  graphics
• Location file system or database
• parameter list for parameterized reports
