Dump Table Contents (DU)

Dump Table Contents

This command is used to set up parameters and data to be accessed by the low-level access routine TBACC.

MOVE 'DU'                   TO xxxx-COMMAND.
CALL 'TBLBASE' USING        TB-PARM
                            xxxx-COMMAND-AREA
                            TBACC-DEF
                            TABLE-AREA.

memcpy( tbCommArea.tbCommand, "DU", 2 );
TBLBASE( &tbParm, &tbCommArea, &tbAccDef, pTableArea );

TBACC-DEF

TABLE-AREA

The contents of the first N rows of the table are moved to TABLE-AREA, where N equals the COUNT value set by the application in xxxx-COMMAND-AREA. The command is normally followed by a call to TBACC. If ERROR 0 is returned, the TBACC-DEF is returned and can be used directly by the TBACC(DK1T0103) subroutine.

ERROR 0068 is returned if the requested N rows is smaller than the number of rows in the table. The first N rows are returned even when N is less than the number of rows in the table.

If this command causes an Implicit Open of the table, the count field is not affected.

The DU command only updates the first 32 bytes of the TBACC DEF parameter (see TBACC-DEF (32 bytes)).
