The **Arguments** object in the standard library allows you to work with Command Line Arguments from inside a Small Basic program. The **Arguments** object includes a **Count** property that gives the total number of arguments passed to the program, and a **GetArgument(index)** operation that allows you to access each of these arguments using their index.

The following program prints out all the prime numbers less than the number passed at the command line.

If (Arguments.Count = 1) Then maxNumber = Arguments.GetArgument(1) If (maxNumber < 2) Then TextWindow.WriteLine("No Primes less than 2.") EndIf For i = 2 To maxNumber CheckPrime() If (isPrime = "True") Then TextWindow.WriteLine(i) EndIf EndFor Else TextWindow.WriteLine("Usage: prime.exe") EndIf Sub CheckPrime isPrime = "True" For j = 2 To Math.SquareRoot(i) If (Math.Remainder(i, j) = 0) Then isPrime = "False" EndIf EndFor EndSub

In this program, Small Basic tries to coerce any passed argument as a number. If you try passing a non-number, the program ends up with “0” and will print out “No Primes less than 2.”
