/* IXPIDX is a pointer to the column's index. IXTPDX contains a */

/* of indirection: a record number points to a record pointer, */
/* which is a structured array of metadata and data pointers. */
/* Record pointers always occupy contiguous ranges of integer */
/* addresses. */
/* The parameter declarations in this file depend on the assumption */
/* that integer pages contain 256 DAS integer words and that the */
/* maximum number of columns in a segment is 100. Record pointers */
/* are stored in integer data pages, so they must fit within the */
/* usable data area afforded by these pages. The size of the usable */
/* data area is given by the parameter IPSIZE which is declared in */
/* ekdatpag.inc. The assumed value of IPSIZE is 254. */
/* The first element of each record pointer is a status indicator. */
/* The meanings of status indicators depend on whether the parent EK */
/* is shadowed or not. For shadowed EKs, allowed status values and */
/* their meanings are: */
/* OLD The record has not been modified since */
/* the EK containing the record was opened. */
/* UPDATE The record is an update of a previously existing */
/* record. The original record is now on the */
/* modified record list. */
/* NEW The record has been added since the EK containing the */
/* record was opened. The record is not an update */
/* of a previously existing record. */
/* DELOLD This status applies only to a backup record. */
/* DELOLD status indicates that the record corresponds */
/* to a deleted OLD record in the source segment. */
/* DELNEW This status applies only to a backup record. */
/* DELNEW status indicates that the record corresponds */
/* to a deleted NEW record in the source segment. */
/* DELUPD This status applies only to a backup record. */
/* DELUPD status indicates that the record corresponds */
/* to a deleted UPDATEd record in the source segment. */
/* In EKs that are not shadowed, all records have status OLD. */
/* The following parameters refer to indices within the record */
/* pointer structure: */
/* Index of status indicator: */
/* Each record pointer contains a pointer to its companion: for a */
/* record belonging to a shadowed EK, this is the backup counterpart, */
/* or if the parent EK is itself a backup EK, a pointer to the */
/* record's source record. The pointer is UNINIT (see below) if the */
/* record is unmodified. */
/* Record companion pointers contain record numbers, not record */
/* base addresses. */
/* Index of record's companion pointer: */
/* Each data item is referenced by an integer. The meaning of */
/* this integer depends on the representation of data in the */
/* column to which the data item belongs. Actual lookup of a */
/* data item must be done by subroutines appropriate to the class of */
/* the column to which the item belongs. Note that data items don't */
/* necessarily occupy contiguous ranges of DAS addresses. */
/* Base address of data pointers: */
/* Maximum record pointer size: */
/* Data pointers are given the value UNINIT to start with; this */

/* are stored in integer data pages, so they must fit within the */
/* usable data area afforded by these pages. The size of the usable */
/* data area is given by the parameter IPSIZE which is declared in */
/* ekdatpag.inc. The assumed value of IPSIZE is 254. */
/* The first element of each record pointer is a status indicator. */
/* The meanings of status indicators depend on whether the parent EK */
/* is shadowed or not. For shadowed EKs, allowed status values and */
/* their meanings are: */
/* OLD The record has not been modified since */
/* the EK containing the record was opened. */
/* UPDATE The record is an update of a previously existing */
/* record. The original record is now on the */
/* modified record list. */
/* NEW The record has been added since the EK containing the */
/* record was opened. The record is not an update */
/* of a previously existing record. */
/* DELOLD This status applies only to a backup record. */

/* DELNEW This status applies only to a backup record. */

/* segment. */
/* SEGDSC is a descriptor for the segment to which data is */
/* to be added. The segment descriptor is not */

/* descriptor will become invalid after this routine */
/* returns. */
/* COLDSC is a descriptor for the column to be added. The */
/* column attributes must be filled in, but any */
/* pointers may be uninitialized. */
/* CVALS is an array containing the entire set of column */
/* entries for the specified column. The entries */
/* are listed in row-order: the column entry for the */
/* first row of the segment is first, followed by the */
/* column entry for the second row, and so on. The */
/* number of column entries must match the declared */
/* number of rows in the segment. Elements must be */
/* allocated for each column entry, including null */
/* entries. */
/* NLFLGS is an array of logical flags indicating whether */
/* the corresponding entries are null. If the Ith */
/* element of NLFLGS is .FALSE., the Ith column entry */
/* defined by CVALS is added to the specified segment */
/* in the specified kernel file. */
/* If the Ith element of NLFGLS is .TRUE., the */
/* contents of the Ith column entry are undefined. */
/* NLFLGS is used only for columns that allow null */
/* values; it's ignored for other columns. */
/* WKINDX is a work space array used for building a column */
/* index. If the column is indexed, the dimension of */
/* WKINDX must be at NROWS, where NROWS is the number */
/* of rows in the column. If the column is not */
/* indexed, this work space is not used, so the */
/* dimension may be any positive value. */

/* $ Particulars */
/* This routine operates by side effects: it modifies the named */
/* EK file by adding data to the specified column. This routine */
/* writes the entire contents of the specified column in one shot. */
/* This routine creates columns much more efficiently than can be */
/* done by sequential calls to EKACEC, but has the drawback that */
