Methods of Randomization of Large Files with High Volatility 1970-03-01 8 .pdf application/pdf 2593 251 69 position, and relative record address ( RRA) in this paper, refers to the computed offset address of a record in the file, relative to the starting address of the file is track 40, a record with RRA = 5 would have its home Direct Access Methods, the system locates that disk address generated file was being occupied by records-this method became unusable; records were then located so far from their original addresses that terminal of the input data, map records uniformly across the available file space. The algorithm which resulted utilizes a pseudo-random number generator, RAND (7) developed at the W.S.U. Computing Center RANDL, N to the purchase order number of the record to be located, and by using Inputs to this program are: a) an algorithm to generate relative record locations; b) a there are six records to map into a direct access file of eight locations. ./cache/5128.pdf ./txt/5128.txt
