Answer 1

Assume you have 3 batch files.

1. ping1.bat which has the content ping 127.0.0.1
2. ping2.bat which has the content ping 127.0.0.1
3. ping3.bat which has the below two lines
   call ping1.bat
   call ping2.bat

If you have all the three batch files in a single folder,(lets say under C:\NewFolder) then if you double click ping3.bat, you won't get any error for sure.

Note: If you don't want to wait for the first command to complete, then use start keyword which just initiate the process and proceed with the next line in the batch file, whereas call will do it sequentially(comes to next line only after the current process completes , start allows parallelism)
To do it parallel use the below two lines of code in the ping3.bat:

start ping1.bat
start ping2.bat
