如何对下列程序用提供的表文件jftj.dbf进行修改
【可在表中插入语文、数学、英语字段】
CLEAR
fz='a10b09c08d07'
ls='语文数学外语'
zhifu='aaddcdadbbabbbc' &&这一句如何用表中字段zifu 替换?
FOR i=1 TO 15 STEP 5
vz = SUBSTR(zhifu,i,5)
jg = 0
FOR j=1 TO 12 STEP 3
zz
= SUBSTR(fz,j,1)
zzz = VAL(SUBSTR(fz,j+1,2))
jg = jg +(LEN(vz)-len(CHRTRAN(vz,zz,'')))*zzz
ENDFOR
?SUBSTR(ls,((i-1)/5)*4+1,4)+":"+STR(jg,4)
ENDFOR
