How to write VBScript from batch?

I have a problem with adding VBScript to a Batch file. I tried this:

@echo off
echo MsgBox("Hello")
echo Do
echo MsgBox("Hello")
echo Loop >>msg2.vbs
start msg2.vbs

But it gave me an error that I used Loop without Do. What am I doing wrong?

Your batch file doesn't magically know which lines you want in the VBScript. Either redirect each echo output (as agriffaut suggested), or run the echo statements in a command block and redirect the entire output of that block (so you don't have to append repeatedly):

(
  echo MsgBox("Hello"^)
  echo Do
  echo MsgBox("Hello"^)
  echo Loop
)>msg2.vbs

Note that for the latter you need to escape closing parentheses inside the block. In this particular case you could just remove them entirely, though:

(
  echo MsgBox "Hello"
  echo Do
  echo MsgBox "Hello"
  echo Loop
)>msg2.vbs

Another option would be using a single echo statement and escaping the line breaks:

>msg2.vbs echo MsgBox "Hello"^

Do^

MsgBox "Hello"^

Loop

Note that the blank lines are required here.

Your Batch script actually only append loop to msg2.vbs file on each run..

You should append all 'vbs' lines from your batch file like this:

@echo off
echo msgBox("Hello") > msg2.vbs    :: > creates file if not exists with: msgBox("Hello")
echo do >> msg2.vbs                :: >> appends line with: do
echo msgBox("Hello") >> msg2.vbs   :: >> appends line with: msgBox("Hello") 
echo loop >> msg2.vbs              :: >> appends line with: loop
start msg2.vbs
