"-29 thesaurus or phrase list, documents mtist be looked up again. The punched- out decks include the appropriate *FIND, *LIKE or *TEDCT card. 4.3. DOCTAPS If the DOCTAP specification is given a tape of binary documents should be mounted on A6. This tape contains documents looked up in an earlier run, as is true also of the documents which follow the *oNLY card on [OCRerr]. The tape on A6 is in a different, more coppact, format, however, which is written by the program [OCRerr]CTAP (6.2) from the binary cards. The tape may contain several sets of looked-up documents. To select the set to be used, a *FII[OCRerr] card should be provided. The *FII[OCRerr] card contains *Yfl[OCRerr] in columns 1-5, a blank in column 6, and either an integer or an alphabetical file name in columns 7-18. If a file name is provided, the set of binary documents identified with that name on the *NAME card produced when the tape was written (part 6.2) is read from A6. If the integer n (punched anywhere in the field) is provided, the nth file is read. If no *FILE card is provided, the physically first file on A6 is used. The *FIIŁ card is placed on A2 following the specifications, but preceding the *sTOP card and the *ONLY card (if there is one). The *FII[OCRerr] card must not appear in the middle of an [OCRerr]glish document, however, nor between a [OCRerr]EXT, *FIND, or *LIKE card and the following document. 4.4. Relevance Jud[OCRerr]ent Data After all documents are read, the next input card must have *SToP in cols 1-5 and a blank in column 6. This card `mist occur e[OCRerr]ctly once on [OCRerr] for each set of instructions, following all [OCRerr]glish and binary documents (if any). It must also occur at the end of each set of documents on
