A data set, such as one created by process engineers, requires that every combination of part numbers, operation numbers, and machine types must form a unique data set name. The part number in this instance is seven digits long, the operation number is three digits, and the machine type is one digit, for a total of eleven digits. However, the subhost computer in which the data is stored allows data set names up to only eight characters long. Thus, it is necessary to convert every combination of the eleven digits into a unique data set name eight characters long in order for a microcomputer to retrieve a data set from the subhost computer. The algorithm for performing this conversion is as follows: Character one of the data set name is a constant alphameric character (such as 'J').
