It is used by the Kuno multiple-path syntactic analyzer. This analyzer is discussed in [9]. The grammar tape itself is not actually written by any program in the SM[OCRerr]RT package; a tape containing the grammar is prepared by the analyzer programs operating independently. This tape is then copied onto the SM[OCRerr] library tape. The card following the syntactic phrase list directs the tape copy. If it begins with [OCRerr][OCRerr]A5 in columns 1-6, a new graaaar tape on AS replaces the old grammar. If it begins with c0FYA6, the old graaaar is used. If U[OCRerr][OCRerr]TA5 appears in cols 1-6, a new grammar is copied from A5 and the old grammar is skipped on A6. T}[OCRerr]e SM[OCRerr]T programs have been run with a graaaar modified to accept noun phrases and prepositional phrases. This permits the syntactic analysis of titles [14]. However, as noted above, the syntactic analysis routines are generally in disuse because of timing problems, since the new, faster analyzer is not yet available. 5.1.5. The Criterion Tree File The fifth file of the library tape consists of the criterion trees, a phrase dictionary in which phrases are defined by a complete set of structural/ seaantic/syntactic specifications. The overall control cards recognized by the update editing criterion tree routine are: ICOPY in columns 1-5, with an optional integer beginning in column 7. The indicated number of trees are copied from A6 to B5. If no number is given, the whole criterion tree file is copied. /SKIP in columns 1-5, with an optional integer beginning in column 7. The indicated number of trees on A6 are skipped (if no number is given, the whole file is skipped).
