Screen Output/Appearance Problems

• All coordinates with respect to placing windows on the screen are based at the coordinates of (0,0). If the screen has 25 rows and 80 columns, the last row is row 24 and the last column is column 79.
  
  
• All coordinates inside the window are relative to the inside of the border and margins. These coordinates are based at (0,0).
  
  
• All output to windows must be done with Vermont Views functions. Standard I/O functions in the standard C library will not work properly within windows.
  
  
• The function vv_init() must be called before using any Vermont Views functions, except vid_setmode(), init_nochk(), and se_initfp().
