TBLT_RETC TBLT_ENTRY BltDataDebumpRecord(TBLT_DH *dhPtr,
ULONG recNo);
dhPtr IO:data file control structure
recNo I:number of record to remove
This routine removes the last physical record from the DBF data file.
If a memo field is being used, all memos associated with this record should
first be deleted with BltMemoDelete().
Only the last physical record can be removed by this routine (where
recNo == TBLT_DH.noRecords). To remove other records use BltDataMarkRecord()
or its macro BltDataDeleteRecord(), and follow that with BltDataPack().
Return: Non-zero indicates an error, otherwise all trace of the record at recNo,
which is always the last record, is removed.
