(1) 日期數(shù)據(jù)：
DATA: Mdata TYPE D.
Mdate = SY-DATUM. “ 如傳回 19971015
Mdate+6(2) = ‘01’ “ Mdate 變成 19971001
Mdate = Mdate - 1 “ Mdate 變成 19970931
(2) 時(shí)間數(shù)據(jù)：
DATA: HOURS TYPE I,
MINUTES TYPE I,
T2 TYPE T VALUE ‘200000’,
T1 TYPE T VALUE ‘183000’.
HOURS = (T2 - T1) / 3600. “計(jì)算有幾小時(shí)
MINUTES = (T2 – T1) / 60. “計(jì)算幾分鐘
3、運(yùn)算符號(hào)：

(1) 算術(shù)符：+ - * / div mod
(2) 比較符：> >= < <= = <> ><
