3.1 The Software Input/Output Manual (SIOM) tells a user how to access, submit inputs to, and interpret output from, a batch or interactive software system that is run by personnel in a computer center or other centralized or networked software installation. 3.2 The SIOM is developed for software systems that will be installed in a computer center or other centralized or networked software installation, with users accessing the system via terminals or personal computers or submitting and receiving inputs and outputs in batch mode. 7.1 This Data Item Description (DID) contains the format and content preparation instructions for the data product generated by specific and discrete task requirements as delineated in the contract. 7.2 This DID is used when the developer is tasked to identify and record information needed by persons who will submit inputs to, and recieve outputs from, software, relying on others to operate the software in a computer center or other centralized or networked software installation. 7.3 This DID is often used with the Software Center Operator Manual (SCOM) (DI-IPSC-81444). This pair of manuals is an alternative to the Software User Manual (SUM) (DI-IPSC-81443). 7.4 The Contract Data Requirements List (CDRL) (DD 1423) should specify whether deliverable data are to be delivered on paper or electronic media; are to be in a given electronic form (such as ASCII, CALS, or compatible with a specified word processor or other support software); may be delivered in developer format rather than in the format specified herein; and may reside in a computer-aided software engineering (CASE) or other automated tool rather than in the form of a traditional document. 7.5 This DID supersedes DI-IPSC-80693.
