Zusammenfassung: | A data-base language called RECALL has been implemented on the Wang 2200 programmable desk calculator. The language was patterned after RETRIEVE, developed by Tymshare, Inc., for its time-sharing network. Differences between the two implementations are very minor. The report describes each command in the language and gives a comprehensive example to illustrate how the entire system can be used. The listing of the program allows the reader to make modifications, if necessary. The RECALL system is implemented on a 2200C calculator with 16k bytes of memory and a model 2230 disk used for temporary storage of the overlay segments needed for running the program. The system assumes that the data bases will be permanently saved on tape cassette. |
