Sorting techniques are compared. Comparison of the ripple sort, bubble sort and the Shell-Metzner sort. A different search technique. How to speed up searching tables for a match. Can save as much as one-half of the search time. It's there, but where. A description of simplified data storage and retrieval techniques, and some tricks-of-the-trade. Using arrays, ragged tables, lists, and other techniques to store large amounts of complex information in limited memory space. BASIC program for SWTP machine will alphabetize a list of up to 99 items (such as names), number the list, and print it out after sorting. The items must be input from the keyboard at the start of the program. QUICKSORT. Programs illustrate the Shell sort and modified Quicksort methods for sorting N elements in an array. Table compares sorting times for 100 elements. Introduction to data base management. A TRS-80 cross-index. A document indexing program cites the document number, the name of the originator, the name of the recipient, and the date of the document. Information is stored on magnetic cassettes. The tapes may then be searched on the index parameters. Written in Level II BASIC. The ELECTRONIC LIBRARIAN. Ambitious program in BASIC-E is used to cross-index journals, magazine articles or other information. Uses a keyword indexing scheme allowing up to 676 different subject headings.
