INFOSH is a program which allows the user to search through data in any file set up through the main INFO programs (IR 004 715) and obtain results of each search in a table format. It functions primarily to facilitate answering questions about data in a file in a way that does not involve manual scanning. It can give answers to questions dealing with trying to identify specific file items that satisfy one or more different conditions. This report describes what INFOSH can and can not do and how to use it. Appendices provide a list of variables used in INFOSH and their functions, a flow chart in INFOSH operation, and sample runs and listings. (DAG)
