ABSTRACT:
A method is disclosed for preserving entered data in an electronic document from being obliterated with additional data. A code address or flag is assigned to each electronic document. The code address identifies the electronic document as modifiable or non-modifiable. If the electronic document is modifiable, entered data may be obliterated or destroyed by entering additional data thereover. If the code address identifies the electronic data as non-modifiable, the entered data is preserved by preventing additional data to be entered which will obliterate the previously entered data. The entered data becomes annotations to the electronic document having a non-destructible format, i.e., color and masking, allowing an operator to freely add additional data without destroying the entered data.
