Semi automate Netscaler CLI command

I wanted to automate the creation of VIP into the netscaler but I currently don't have time to learn how to powershell+nitro all of it but had an urgent need to standardise the creation of new VIP. So to go around that time limitation, I have created a batch file that semi-automate the process of creating new VIP into the Netscaler so that everything that gets created in the Netscaler follow the same standard. The batch file ask you some basic question and return you command that you have to copy/paste into the Netsclaer CLI (I connect to the netscaler using PuTTy). The script is not 100% dummy-proof so if you enter wrong information in a field the batch file does not double check all that you enter and your command output will not be good.
Save the following into a text file with extension .bat and run it.
