The new record flag indicates if a record has been cleared and not written to disk yet. The record manager uses this flag to decide if a record should be added or updated.
The new record flag is set when the record handle is allocated or when CTRecord::Clear() clears the record. The new record flag is cleared when a record is read from disk by calling one of the CTRecord::First(), CTRecord::Last(), CTRecord::Next(), CTRecord::Prev(), CTRecord::SeekRecord(), CTRecord::Find() or CTRecord::FindTarget() methods.
Use CTRecord::SetNew() to set the record new flag or CTRecord:IsNew() to check if a record is new or not.

A record is only written to disk if the edited record flag is set. This flag is set when the record buffer is modified with a call to one of the CTRecord::SetFieldAs...() methods or by calling CTRecord::SetEdited() method. Use CTRecord::IsEdited() to check if a record has been edited or not.

This property holds the current record offset of a record. If a record is cleared, the record offset property is zero. All records in a table, even the first record, will have a record offset value greater than zero.
You can retrieve the record offset value by calling CTRecord::GetRecordPos() method. You can set the record offset property, and load the record data at the offset, by calling CTRecord::SeekRecord().

Use CTRecord::GetRecordCount() to retrieve the total number of records in a table. This is a read only property.
// check if table is empty
if (ARecord.GetRecordCount() > 0)
{
printf("Table is not empty\n");
}

Use CTRecord::GetRowid() method to retrieve the ROWID value for the current record. This is a read only property.
// retrieve the first record rowid
CTROWID rowid = ARecord.GetRowid();
