Type Compatibility of .NET and JVM COBOL with Other Managed Languages

Many managed COBOL (.NET COBOL and JVM COBOL) types have a strict correspondence with managed types in other languages, such as binary-long and float-short. For those that don't have a correspondence, there are alternatives.

The following table lists the correspondence between the .NET and JVM COBOL types and classes and types in other managed languages.

Managed COBOL (.NET or JVM COBOL)	.NET type	JVM type	C# keyword	Description
Integer types:
binary-char	System.SByte	byte	sbyte	An 8-bit signed integer Not CLS-compliant
binary-char unsigned	System.Byte		byte	An 8-bit unsigned integer
binary-short	System.Int16	short	short	A 16-bit signed integer Not CLS-compliant
binary-short unsigned	System.UInt16		ushort	A 16-bit unsigned integer
binary-long	System.Int32	int	int	A 32-bit signed integer
binary-long unsigned	System.UInt32		uint	A 32-bit unsigned integer Not CLS-compliant.
binary-double	System.Int64	long	long	A 64-bit signed integer
binary-double unsigned	System.UInt64		ulong	A 64-bit unsigned integer Not CLS-compliant
Floating point types:
float-short	System.Single	float	float	A single-precision (32-bit) floating-point number
float-long	System.Double	double	double	A double-precision (64-bit) floating-point number
Logical types:
condition-value	System.Boolean	boolean	bool	A boolean value (true or false)
Other types:
character	System.Char	char	char	A unicode (16-bit) character
decimal	System.Decimal	see JVMDECIMAL.	decimal	A 96-bit decimal value
Class objects:
object	System.Object	java.lang.Object	object	The root of the object hierarchy
string	System.String	java.lang.String	string	An immutable, fixed-length string of Unicode characters
Collection types:
list	System.Collections.Generic.IList<T>	java.util.List		An ordered collection of items
dictionary	System.Collections.Generic.IDictionary<TKey, TValue>	java.util.Map		A mapping of keys to values
set	System.Collections.Generic.ISet<T>	java.util.Set<T>		An unordered collection of items
