Question

VB的英文逗号有什么用?
Private Sub command1_click()
Dim n As Integer
Dim k As Integer
Dim a As Integer
Dim isprime As Boolean
For n = 100 To 300
For a = 2 To Int(Sqr(n))
If n Mod a 0 Then
isprime = True
Else
isprime = False
Exit For
End If
Next a
If isprime = True Then
If k Mod 5 = 0 Then Print
Print n,
k = k + 1
End If
Next n
Print
Print "100到300间所有素数的个数是：" & k
End Sub
如上,如果把倒数第七行的逗号去掉,就是每行只有一个值了.
请大家最好可以复制到VB里看一下,
