DBCS Large Character Strings

DBCS large character strings enable you to store large amounts of DBCS data in columns.

Host Variable Formats

01 dbcs1.
   49 dbcs1-len          PIC S9(9) COMP-5.
   49 dbcs1-data         PIC N(32000) USAGE DISPLAY-1.

01 dbcs2.
   49 dbcs2-len          PIC S9(9) COMP-5.
   49 dbcs2-data         PIC G(32000).
  • The level number for group items containing only two elementary items must be 49. The first item is a four-byte field declared with usage COMP or COMP-5 that represents the effective length of the character string. The length field can be signed or unsigned. The second item is a PIC n DISPLAY-1 or PIC G data type, where n is an integer representing the length of the field that holds the data.
  • SQL statements must reference the group name.
