Ahh... looks like we have a small bug in MonkeyMax then :P

BlitzMax:
Local a:Int = -858993460 ' binary: 11001100110011001100110011001100
Local o1:Int = a Shl 6 ' left shift
Local o2:Int = a Shr 6 ' unsigned right shift
Local o3:Int = a Sar 6 ' signed right shift
Print ("a   = "+a)
Print ("ol1 = "+o1)
Print ("ol2 = "+o2)
Print ("ol3 = "+o3)

Outputs:
a   = -858993460
ol1 = 858993408
ol2 = 53687091
ol3 = -13421773

Monkey:
Function Main()
  Local a:Int = -858993460 ' binary: 11001100110011001100110011001100
  Local o1:Int = a Shl 6 ' left shift
  Local o2:Int = a Shr 6 ' signed right shift
  'Local o3:Int = a Sar 6 ' signed right shift
  Print ("a   = "+a)
  Print ("ol1 = "+o1)
  Print ("ol2 = "+o2)
  'Print ("ol3 = "+o3)
End

Outputs
a   = -858993460
ol1 = 858993408
ol2 = -13421773

I converted this Java example:

/**

public class ShiftOperations {
   public static void main(String[] arg) {
      int a = -858993460; // binary: 11001100110011001100110011001100

      int o1 = a << 6;  // left shift
      int o2 = a >> 6;  // right shift
      int o3 = a >>> 6; // unsigned right shift
...
