title: basic perl, command prompt question: how to enter the next command after returning "perl" accidentally
body: <p>this may sound incredibly naive and stupid,
  i'm new to programming</p>
  
  <p>in command prompt after returning perl alone without any command, i'm not able to enter the next command. i'm struck there </p>
  
  <p>i mean C:\users\sam>perl   </p>
  
  <p>how do i get to 
  "C:\users\sam>"  again
  its very frustrating thanks</p>
