describes work perforued under NSF.Grant Nos.IST-7911190 and.IST-8111497,and covers the perfods October 1,1979 toSeptember 30,1981 and January 15,1982 to October 31,1983,respectively.Noattenpt is made to report,chronologically,the activity under these twoefforts.However,the work performed can be generally described as follows:  \n1979-1981 .Major software upgrade;expansion of experimental system from 6to 15 controlled vocabularies;eva luatfon of varfous experimentalsyitch ing stacks;conceptualization of expression -level switch-、ing.  \nMajor feature faplementation(related terms);new user interfacemenu access);field eva luatfon of VSS;update of 1979 on-1inesurvey.  \n1982-1983  \n# ACKNOMLEDGEMENTS\n\nThe authors gratefully acknowledge the support of the National,Science
