- If nnnn appears, the cards sequenced from mmmm to nnnn inclusive are deleted. Cards which follow the *NOTES card are then matched one-for-one with cards on the master file following sequence number nnnn. Columns 36-72 of these cards replace columns 36-72 of the corresponding master file card. Columns 1-35 of the card are not disturbed.
- If nnnn does not appear, the commentary replacement begins with the card sequenced mmmm.
- The process terminates with occurrence of another control card, or when the file 'name' is exhausted of cards.
Care should be exercised in using the *NOTES card in order to avoid intrusion into the scope of a minor control card which follows. For, since the *NOTES card results in passing cards of the master tape beyond the deletion (if any), the first sequence number which can enter into the next change is:
p+mmmm or p+nnnn+1
where p is the number of cards within the scope of the *NOTES card. For convenience, the operation may be written *N instead of *NOTES.
*END CARD
Upon recognition of the major control card:
8
*END
the changes applicable to the last file referenced by a major control are completed, the remainder of the master tape is copied onto the new master (is any) and control is returned to CTM. An *END card is simulated if an end-of-file condition is encountered in the input.
CHANGE STATUS INDICATORS
For convenience in comparing the updated tape with the old, the change status of every card in the file referenced by a major control card is indicated in column 83 on both the new master and second output tapes. If this column contains:
- A blank, the card was not changed;
- An asterisk (*), the card was inserted;
- A dollar sign ($), the card was commented;
- A plus sign (+), the card is an insert on the second output tape only;
- A slash (/), the card is the first one following a deletion.
