- If nnnn does not appear, no deletion occurs, and the cards are simply inserted before the card sequenced mmmm.
'Name' must agree with the file identifier or the card is not effective. Leading zeros may be suppressed in the variable field for both mmmm and nnnn, and a blank may be used in place of the comma. For convenience, the operation may also be written *A instead of *ALTER.
*INSAS CARD
The minor control card
1 8 16
Name *INSAS mmmm
is used when an insertion is to be made only on the second output tape. Cards following the *INSAS card are inserted on this tape prior to the card sequenced mmmm. The sequence number is not advanced during the insertion, so that the sequence numbers of cards which appear on both the master and second output tapes always agree. For convenience the operation may also be written *IA instead of *INSAS.
This type of insertion is useful if the second output tape is intended for assembly input, since LIST, UNLIST, END and other special cards can be placed where desired, without affecting the file kept on the master tape.
Another very important use is to create *MAIN type control cards when the second output tape is intended for use as the input of another symbolic update. A control card cannot normally be placed on an output tape, since recognition of such a card terminates any modification sequence and begins another. For this reason, a card under the scope of an *IA card which has the character combination + in columns 1-3 is special. For such a card, columns 1-6 are replaced by columns 25-30, and columns 25-30 are blanked out before the card is placed on the second output tape.
*NOTES CARD
When modifying a file of symbolic instruction cards, it is sometimes convenient to replace only the commentary field of certain cards. The minor control card
1 8 16
Name *NOTES mmmm [,nnnn]
is for this purpose, and functions as follows:
- Cards up to, but not including, sequence mmmm are placed on the output tape(s).
