Type assignment

The table below presents an overview of the Java classes present in the framework together with a brief description of the COBOL types for which the classes are used.

Java class	Description
DataType	Basic class for all conversion classes
CobolRecord	Basic class for COBOL structures
PicX	For alphabetical/alphanumerical COBOL types: PIC X(n)
PicN	For national COBOL types: PIC N(n)
Pic9	For positive, integer numerical COBOL types: PIC 9
Pic9COMP	For integer numerical COBOL types: PIC S9(n) and PIC 9(n) USAGE [COMP, BINARY, COMP-5]
PicU	For COBOL types for which Cobol2Java offers no special data conversion classes. The data is made available in the Java program without conversion as a byte array.

The directory api-doc contains the documentation for these classes.

The table below indicates the support provided for the various COBOL types and clauses:

COBOL clause	Java support
Data structures with level numbers	CobolRecord
Pic X (n) (alphanumerical)	PicX
Combinations of A, X, 9 (not only 9)	PicX
Pic 9 (n) (numerical)	Pic9
Pic N (n) (national)	PicN
BINARY, COMP, COMP-5	Pic9Comp for PIC9(1)to PIC9(18) Not supported: PIC 9(19) to PIC 9(31) is mapped to PicU
COMP-1, COMP-2, COMP-3	Not supported.
Alphanumerical, ready for printing Alphabetical, ready for printing	Mapped to PicX. The preparation mask is ignored.
Numerical, ready for printing	Not supported. Mapped to PicU.
BLANK WHEN ZERO	Not supported. Mapped to PicU.
INDEX	Not supported.
POINTER; PROCEDURE POINTER, OBJECT REFERENCE	Not supported.
JUSTIFIED RIGHT	PicX, ignored.
SYNCHRONIZED	Supported.
Level number 77	Supported.
OCCURS	Limited support. Dynamic arrays (OCCURS DEPENDING ON) are created with a fixed length. OCCURS INDEXED BY, OCCURS KEY IS is not supported.
REDEFINES	Supported.
RENAMES	Supported.
