set talk off
dime a(7)
use xsda
s=0
for i=3 to 5
scatter to a
s=s+a(7)
skip
endfor
"s="+str(s)
return

set talk off
dime a(7) &&定义一个一维数组,此数组有7行数据组成
use xsda
s=0
for i=3 to 5 &&这里只够明白是三次循环,似乎I没有什么意义
scatter to a &&从当前记录中复制数据到一个数组,因为此行命令了省略了FIELDS FieldNameList ,所以将从所有字段中复制值,即将当前记录的值依次赋给a(1),a(2),……,a(7).
s=s+a(7) &&进行累加,但此a(7)指的是数组a的第7行数据,由上行命令中赋值,其值由表XSDA的第7个字段的值
skip
endfor
"s="+str(s)
return

set talk off SET TALK OFFSET TALK OFFSET TALK OFF set talk off和set talk on如何使用请问Vf 中的 set talk on/off vfp中set talk off/on和set safety VF中,程序开头的SET TALK OFF 　　　　　　　　CLEAR SET TALK OFF,X=2 ,DO WHILE X SET TALK OFF 这个语句有什么作用? set out,set up,set off,set SET TALK OFF STORE 1 TO A,B DO WHILE A set talk off clear s=o i=1 最好带中文的在vf数据库里,b->或a->是什么意思?recno()的用法?set talk off是什么用法?
