Variants§

Display

Binary

NativeBinary

COMP-5: binary, never truncated to the PICTURE.

BinaryChar

GnuCOBOL’s and Micro Focus’s BINARY-CHAR [SIGNED|UNSIGNED]: one byte of binary, no PICTURE.

Fields

§signed: bool

CompX

Micro Focus’s COMP-X: binary in the fewest bytes that hold the PICTURE’s digits, or n bytes for PIC X(n).

Packed

Float1

Float2

National

Dbcs

DISPLAY-1: DBCS characters, two bytes each.

Pointer

Index

ObjectReference

ProgramPointer

FUNCTION-POINTER or PROCEDURE-POINTER.
