# What are the different ways of invoking a command?

1. To invoke command synchronously call the command with suffix Now

   grab[LotteryCommandSet].createNow(lotteryName = "metastay", amount = 80000)
   

2. To invoke command asynchronously call the command with suffix ToQ

   grab[LotteryCommandSet].createToQ(lotteryName = "metastay", amount = 80000)
   

3. To execute the command code only when pre-conditions are satisfied, call the command with suffix IfPrePass

   grab[LotteryCommandSet].createIfPrePass(CreateCommand.Input(lotteryName = "metastay", amount = 80000))
