BLICURDSK        (Clipper)
------------------------------------------------------------------------------

  Function : Number of disk loads for current procedure

  Syntax   : nlLoads = BLICURDSK()

  Return   : Number of times the overlay manager has loaded the
             current overlaid procedure from disk

  This function returns the number of times the current overlaid procedure
  has been loaded from disk since the program started. It can be used to
  identify procedures which are repeatedly loaded from disk, with a view
  to improving application performance by moving them to the root or by
  increasing the size of the overlay cache.

  When the 5.01 paging system is enabled Clipper overlays are not managed
  by Blinker, so this figure is not applicable.

  Example  :
  * Get the number of loads of the current
  * procedure
  *
  ? "This procedure has been loaded from disk "
  ?? BLICURDSK(), " times"
