The Occupational Shortages Reporting System (OSRS) is a computerized system developed to produce quick and accurate reports on occupational shortages for given time periods and given occupations in Texas. The system's salient features are: easy and fast retrievability of information; expandability of the data base (from the present 1,254 occupations coded according to the United States Department of Labor's Dictionary of Occupational Titles); and ability to project future shortages from the analysis of past data. The guide describes the Input Subsystem, explaining the three different types of input data (occupational description cards, city name cards, and occupational shortage cards) and their method of coding and preparation, and illustrating their exact layout forms. It next discusses the Computer Subsystem, centering on the generation of a data base which contains all available information on occupational shortages and including the system flowchart and methodology of programing. Finally the guidelines describes the Output Subsystem, explaining and presenting a sample of the output report on occupational shortages. (Author/JR)
