F. Data Types
In DB2 the LONG VARGRAPHIC data type can have 0 to 16,357 characters of 16-bit Double Byte Character Set data in variable length format for 32K pages, or 2,028 DBCS characters for 4K pages of storage. With DBCS, each 2 bytes of data represents a graphic character. This data type is also rarely used. Consult your RDBMS systems manual for further details.
Example: COL1 LONG VARGRAPHIC(1000)
COL1 has up to 1000 bytes of up to 500 variable double-byte characters.
In COBOL: 05 COL1-GROUP.
49 COL1-LENGTH PIC S9(9) COMP.
49 COL1 PIC G(1000) DISPLAY-1.
In COBOL, G(1000) means 2,000 bytes of 1,000 DBCS characters.
