A Data Handling System is described which handles on-site water quality survey data measured by the Army. A sequence of programs is often executed to complete a given data handling operation. OS8 BATCH is used to automate the specification of this sequence of operation via a BATCH input file. OS8 BATCH provides users of the system with a batch processing monitor that is integrated into the OS8 Monitor structure. Several system tables are used by the system software to define a particular data handling application to the system. The system definition file SYSDEF.AR provides information which includes lists of valid ID tags, upper and lower limits for measurement values, data formats, and various heading and column information used during report generation. The translation table file TRNTBL.AR contains the translation tables for the mark sense cards. The method file METHOD.AR specifies for each parameter the particular data conversion algorithm within the function file FNCTN.AR to use on input. The data files and information files are OS8 BASIC numeric files while all other files are OS8 ASCII files. The ID information within these numeric files are 6-bit positive integers. OS8 BASIC user functions are provided to pack and unpack these 6-bit integers within a 36-bit floating point variable. In addition, OS8 BASIC user functions are provided for formatted output, interization, and PDM-70 input. The chapters within this manual include a discussion of the implementation of the data handling programs, file formats, mark card design, and industry compatible type formats.
