  • The level number for group items containing only two elementary items must be 49. The first item is a 4-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 X(n) data type, where n is an integer representing the length of the field that holds the data.
  • SQL statements must reference the group name.
