■ This error can occur when there are too many active
  subroutine, FUNCTION, and SUB calls, or when a recursive
  FUNCTION procedure is nested too deeply.
 
■ Possible solution:
 
  • Change the structure of your program or use the CLEAR
    or STACK statement to increase the program's allotted
    stack space.
 
■ This error cannot be trapped.
