Total cards submitted: BCD 12, binary 2, total i[OCRerr]. [OCRerr]st of the production runs made with SM[OCRerr]T are of this size. 8. Miscellaneous SM[OCRerr]T is frequently changed and revised; thus writeups may differ. The current writeup supersedes the ones included in reports ISR-7 and ISR-8 completely, and it supersedes report ISR-9 wherever the present writeup differs from the one in ISR-9. S[OCRerr]RT is written in Fortran fl and in FAP. With all its subroutines, the programs include approximately 30,000 source cards and 5,000 binary cards. 8.1. Size Limits The thesaurus may consist of any number of English stems; however, only 32,000 significant concepts are allowed. The program can address up to 250,000 documents; however, the capacity of the intermediate tapes will be exceeded before this point. Assuming that M[OCRerr]CTAP is used to prepare the input document tape, about 25,000-100,000 documents (depending on their length) is a probable practical limit. If one insists on submitting documents on cards, about 1500-2000 documents is all will fit. The only truly significant limitation may be expected to be the fact that only fifty requests can be processed in one c[OCRerr]z[OCRerr]uter run. 8.2. Timing The following timing estimates are approximations derived from our
