  Syntax   : nlVal = BLICURCAL()

  Return   : Total number of calls to the current overlaid procedure

  This function returns the number of times the current overlaid procedure
  has been called since the program started. It can be used to identify
  procedures which are called frequently, with a view to optimizing them
  or rewriting them in C or ASM.

  Note: This function is only active if the BLINKER CLIPPER PROFILE ON
  command was specified at link time, otherwise it returns zero.

  Example  :
  * Get the number of calls to the current
  * procedure
  *
  ? "This procedure has been called "
  ?? BLICURCAL()," times"
