| 8.6 Update 
              the Windows Batch File
              We need to update the runvcast.bat file to take care of the 
              new features. 
              The Lesson 6 Batch 
              File 
              This is the runvcast.bat file under the 
              folder C:\Call List. 
                
              REM delay for 30 secondsREM use ping command as a workaround since there is no sleep command
 
 ping 127.0.0.1 -n 30 -w 1000 > NUL
 
 REM now launch broadcastbyphone
 REM add -noexit if you want to keep the program up after broadcast
 
 "C:\Program 
              Files\Voicent\BroadcastByPhone\bin\vcast.exe"
 "C:\Call List\mylist.voc"
 -startnow -cleanstatus
 Here the call list is hard coded to be "C:\Call List\mylist.voc" 
              The New Batch File 
              
              REM delay for 30 secondsREM use ping command as a workaround since there is no sleep command
 
 ping 127.0.0.1 -n 30 -w 1000 > NUL
 
 REM choose the correct call list file
 
 for /L %%a in (0, 1, %1) do shift
 set selectedfile=%1
 
 REM now launch broadcastbyphone
 REM add -noexit if you want to keep the program up after broadcast
 
 "C:\Program 
              Files\Voicent\BroadcastByPhone\bin\vcast.exe"
 %selectedfile -startnow -cleanstatus
 
              Here is call list file choice is passed in as the first argument, 
              and all the call list files are passed in after that. For example, 
              one might invoke the batch file as: 
              
              runvcast.bat 1 "C:\Call List\mylist A.voc" "C:\Call 
              List\mylist B.voc" 
              That command will launch BroadcastByPhone using mylist B.voc.
