ABAP--如何获取ABAP的程序的调用堆栈

		
REPORT demo_mod_tech_perform_int .
DATA: num1 TYPE i,
      num2 TYPE i,
      sum  TYPE i.
num1 = 2. num2 = 4.
PERFORM addit.
FORM addit.
  sum = num1 + num2.
  PERFORM out.
ENDFORM.                    "addit
FORM out.
  field-symbols: <fs> type any.
  data l_cstack_tab  type SYS_CALLST.
  WRITE: / Sum of, num1, and, num2, is, sum.
  CALL FUNCTION SYSTEM_CALLSTACK
    IMPORTING
      et_callstack = l_cstack_tab. " internal table
* l_cstack_tab 里就是abap的调用堆栈    
ENDFORM.                    "out
