Rec and xRec

In the Table and Page objects, the system automatically provides us with the system variables, Rec and xRec. Until a record has been updated by MODIFY, Rec represents the current record data in process and xRec represents the record data before it was modified. By comparing field values in Rec and xRec, we can determine whether changes have been made to the record in the current process cycle. Rec and xRec records have all the same fields in the same structure as the table to which they relate.
