CURRENT_ROW
     Returns an integer that is the screen line on which the cursor is
     located.  This does not reflect any movement of the current position
     that has occurred within a procedure in which CURRENT_ROW is used
     unless the built-in UPDATE (window) precedes it.
  Syntax
     integer := CURRENT_ROW
  Example
     my_cur_row := CURRENT_ROW;
     Stores in the variable MY_CUR_ROW the integer for the current row.
