Pracniques: simulation of Boolean functions in a decimal computer

When items are made up of a variable number of charac~r~, each containing the same number of bits, certain control information (partition symbols) is inserted to mark their sepa~c~fions. Since errors in identification of these control characters ccm lead to serious trouble, methods of protecting these symbols are indicated. A 6-bit code assignment of alphanumeric characters for fixed worddength computers is given and its ~,vi~ability for error detection and variableJength item manipu~ttlon is shown. Also indicated is its flexibility during certain arithmetic operations.
