Item Description
Coding Methods - Specific methods of alphabetic and numerical coding are discussed; also the way in which they may be developed and applied... -- includes sequence codes, block codes, group classification codes, significant digit codes, final digit codes, mnemonic codes, numerical-alphabetic codes - partial sequences, complete sequences; alphabetic derivation codes; more; plus bibliography of other IBM coding publications

Random Number Generation and Testing - Random sampling, simulation studies, Monte Carlo methods, have been in use for many years... applications requiring random numbers are becoming more important and more common in business and industry as well as purely scientific areas... this manual has been prepared which gives the mathematical development of the power residue method, outlines computer techniques for implementing it, and also offers brief comments on other methods... -- includes Number Theory background for the Power Residue method; Statistical considerations; Notes on other methods; appendix, programming the power residue method; references (1959).
