These statistics include a count of the number of tokens processed; the number of types found; the number of types with only one token, two tokens, three tokens, etc., up to the number of times each type occurred on the restriction (or selection) list. Finally S[OCRerr]CCER writes out the time it took to process the text and exits. D. The Cutput Format All of the output produced by S[OCRerr]CCER is written on the [OCRerr]UTPUT tape in blocked BCD records of varying length. This tape includes a carriage control character for each line and is meant to be printed off-line with a printing pro[OCRerr];am capable of handling blocked records and printer carriage control. 3. Tape Usage A. Control Cards The c[OCRerr]ntrol cards for each run of S[OCRerr]CCER must be included as DATA cards on the system input tape, [OCRerr]. S[OCRerr]CCER always reads these card images from A2 before beginning to process the text. B. The INPUT, [OCRerr]UTPUT, and SMRTAP Tapes As explained in Fart [OCRerr], the INPUT tape contains card L[OCRerr]ges of the text to be processed. This tape may be mounted on any tape unit except those used for the [OCRerr]UTPUT and SMRTAP tapes. The most convenient unit to use for the INPUT tape may be A2. In this case the cards of the text are simply subiutted as DATA cards ilmiLediately following the control cards on A2. The logical tape number of the INPUT tape is controlled by the I[OCRerr][OCRerr]PLJT control card. The [OCRerr]UT?UT tape contains the listing of the text and the concordance,
