1、插入內表行:
*插入內表行: DATA: BEGIN OF man, name(20) TYPE c, high TYPE p DECIMALS 2, weight TYPE p DECIMALS 2, END OF man. DATA: man1 LIKE TABLE OF man. man-name = '張參'. man-high = '1.68'. man-weight = 120. INSERT man INTO TABLE man1. man-name = '劉志'. man-high = '1.78'. man-weight = 160. INSERT man INTO TABLE man1. LOOP AT man1 INTO man. WRITE: / man-name,man-high,man-weight. ENDLOOP. ULINE. man-name = '錢華'. man-high = '2.22'. man-weight = 220. INSERT man INTO man1 INDEX 3. LOOP AT man1 INTO man. WRITE: / man-name,man-high,man-weight. ENDLOOP.
