ISR11 Operating Instructions for the SMART Text Processing and Document Retrieval System chapter M. E. Lesk Harvard University Gerard Salton Use, reproduction, or publication, in whole or in part, is permitted for any purpose of the United States Government. ii-8 Specification input always appears on the monitor input tape ([OCRerr]RTRAN logical tape 5), even if SM[OCRerr]T tape ATWO is reassigned to another unit. This exception to the tape addressing system is made to permit the program to get started. One c[OCRerr]puter job may involve several sets of specifi- cations, each of which initiates a processing sequence. In this case, each set of specifications is followed by the data required by that set of instructions. The AGAIN specification (see part 3.8) causes the system to expect a second set of instructions and data following the first set. [OCRerr]ch section of a SM[OCRerr]T processing run begins with the specifications for that section. The specifications are punched in columns 1-72 of as many cards as are needed. A specification consists of an alphabetic word which identifies the specification, followed by its Ilvalue?t if it is not an "on/off[OCRerr]1 specification. The names and meanings of all specifi- cations, and their allowed values, are given in part 3. Whenever a specification differs from the normal value for the item specified (see Table 2), the user z[OCRerr][OCRerr]st punch the specification and the value (if any) on the specification cards. Specifications which are given their normal value may be omitted, or may be punched to i[OCRerr][OCRerr]rove the clarity of the listing, if the user so desires. Any specification may be punched anywhere on a card. However, no specification may be broken between two cards, nor may a specification and its value appear on different cards. The specifications are sepa- rated by one or more blanks; the value of a specification should follow the specification itself separated by one or more blanks. If the value of a specification is a number, care nrust be taken to punch it correctlye If the value of a specification is restricted to integers,
