The standard type aliases in Oxygene are defined in the virtual RemObjects.Oxygene.System (.NET) or com.remobjects.oxygene.system (Java) namespace, which is in the scope by default, along with Compiler Magic Functions.

Alias	.NET Type	Java Type
Byte	System.Byte	com.remobjects.oxygene.system.SByte
Boolean	System.Boolean	com.remobjects.oxygene.system.Boolean
Char	System.Char	com.remobjects.oxygene.system.Char
String	System.String	java.lang.String
WideChar	System.Char	com.remobjects.oxygene.Char
WideString	System.String	java.lang.String
ShortInt	System.SByte	com.remobjects.oxygene.system.SByte
Word	System.UInt16
SmallInt	System.Int16	com.remobjects.oxygene.system.Int16
Integer	System.Int32	com.remobjects.oxygene.system.Int32
Cardinal	System.UInt32
LongWord	System.UInt32
Int64	System.Int64	com.remobjects.oxygene.system.Int64
UInt64	System.UInt64
Single	System.Single	com.remobjects.oxygene.system.Single
Double	System.Double	com.remobjects.oxygene.system.Double
NativeInt	System.IntPtr

Notes for Java

Java has no support unsigned value types
all value types are in the virtual com.remobjects.oxygene.system namespace
the types in the java.lang namespace are reference (i.e. class) types; they are used for the nullable versions of the regular value types:
- e.g.: nullable com.remobjects.oxygene.system.Boolean is java.lang.Boolean.
The java.lang namespace is in scope by default, but com.remobjects.oxygene.system has higher precedence, so the Pascal types are accessible by default.
