(MERG Merge the new suffixes which follow with the old list. (SKIP Same fLmction as (ORIG, except that A6 is spaced over the old file. The suffix cards required for the (ORIG, (DUFL, and (MERG options are punched as follows. Each card contains one suffix identified by its number, and the list of partial homographs for this suffix. The suffix number (associated with the suffix by the cards described in part 5.1.1) is punched anywhere in columns 1-6, and the various possible partial or complete homo- graph codes are punched in six-column alphabetical fields beginning in column 7, using the leftmost fields first. The partial homographs are alphabetic, with the unneeded characters replaced by zeros. For example, the Kuno homograph for a plural noun is [OCRerr]UP. A noun stem, in the SMART dictionary, is given the syntactic code number 70, corresponding to [OCRerr] (note as before that 0 is "zerott while [OCRerr] is the fifteenth letter of the alphabet). The suffix !1[OCRerr]I? has a partial homograph OOOPO. When stem and suffix are combined, the complete homograph [OCRerr]UP is formed. The stem RECTI, to take another example, has the syntax number 043, which corresponds to OTlO. When combined with the suffix FlED, which has the suffix homograph VOOC (among others), a correct homograph VTlC is obtained for RECTIFIED. The remaining hcmographs are obtained from the other suffix homographs; they are ADJ (obtained completely from the suffix) and PTl (OTlO + Poo 0 = PTi) The partial homographs of some sample suffixes are shown in Table 5. 5.1.4.
