What is the difference between Sequential and Randomaccess modes of STATISTICA BASIC?
Sequential mode treats the STATISTICA dataset like a database, executing the entire STATISTICA BASIC program once for each record (case) of the database. The consecutive order of processing records can only be changed by using the Jump(x) command. Randomaccess mode treats the STATISTICA dataset like a spreadsheet, with all values contained in the predefined array DATA(i,j), where i represents the variable (column) number and j the case (row) number within the spreadsheet. In Randomaccess mode, the STATISTICA BASIC program is executed once and any data cell may be accessed by referencing both the variable and case numbers. Review the respective topics in the Electronic Manual for a discussion of the specific advantages and applications of the two modes.
