Really became flooding.. It turns out the key is to control the layout...

But the layout problem is solved, :) Using Tab instead of spaces can do it. You don't need to spend effort on layout.

Tab cannot be displayed correctly in the forum...???

Needs to be studied... Absorb

Like me who can only do dead work, ECHO output...

qjbm uses the Tab key to control typesetting, which has streamlined a lot of code, great.

I've seen the power of batch commands.

The typesetting of the brother on the 16th floor is still not as neat as the building owner's. Personally, I think the building owner's is perfect.

I think it can be simplified further.

16th floor has prompted: Tab cannot be displayed correctly in the forum

So you need to replace the space between !h! and <nul in the copy with the space of the Tab key

set /p=%%i×%%j^=!h! <nul

The code of spiegboy is very good, and extra points are given.

I'm just a new member of this forum. I have many things I don't understand. Please take care of me. At the same time, I hope those who are willing to take apprentices and have good interpersonal relationships and kind hearts can add my QQ: 453803302.
Thanks a million!

The moderators and Brother 16 wrote really well. When I just came in, I couldn't write either. Today I can also write one.

Ask, I'm a newbie. Just follow what the person above said, using **.XXX >**.XXX can implement the output, right? Then, for example, when I want to output a file, as long as I enter a file name, it can help me output it to a corresponding TXT file (or a fixed one like 1.TXT). How to do it?

Why do you need to press Enter?

I saw this post today. Here's a VBS version of the multiplication table from 1 to 9:

1. Dim i, m, s
   
2. For i = 1 To 9
   
3. s = s & vbLf
   
4. For m = 1 To i
   
5. s = s & m & "×" & i & " = " & Left(i * m & " ", 2) & Space(2)
   
6. Next
   
7. Next
   
8. MsgBox s,,"Multiplication Table from 1 to 9"
