title: In batch files calls to executables are sequential or not?
body: <p>Let say ,I have a batch file and I have three commands like:</p>
  
  <p>Execute A process --- Step 1
  Execute B process --- Step 2
  Execute C process --- Step 3</p>
  
  <p>So,if my step 1 takes time to execute then will the control wait for its completion and then go to Step 2 or all the steps may gets executed in parallel?</p>
