分割字符，获取循环索引

1.系统变量SY-INDEX与SY-TABIX是用来记录循环的次数或者索引的 SY-INDEX在DO....ENDDO中是有效的 SY-TABIX在LOOP....ENDLOOP中及READ内表时获取相应的索引 2. READ TABLE INDEX . 下面因没有定义结构，sy-tabix无用。 data:p_lines type i. data:p_lines1 type i. data:p_lines2 type i. lv_str = '/This/is/a/test./'. SPLIT lv_str AT '/' INTO TABLE lt_split_table. DESCRIBE TABLE lt_split_table LINES p_lines. READ TABLE lt_split_table index 2. if sy-subrc = 0 . write : lt_split_table . endif. p_lines1 = p_lines - 1 . READ TABLE lt_split_table index p_lines1 . write : lt_split_table . p_lines2 = p_lines - 2. READ TABLE lt_split_table index p_lines2 . write : lt_split_table .
