维护文件3.0版是PAN AIR软件系统的指南，该系统使用高阶面元法计算几乎任意形状物体周围的亚音速或超音速线性势流。该文档描述了整个系统和系统的各个程序模块。对于程序的维护、更新和修改给出了足够的细节。假设读者熟悉编程和CRAY计算机系统。除了PAN AIR库中存在的几个CAL语言子程序外，PAN AIR系统用FORTRAN 4语言编写。结构化编程技术用于提供代码文档和可维护性。CRAY 1 S、1 M和X-MP计算系统上的操作系统为COS 1.11、COS 1.12、COS 1.13和COS 1.14。该系统由数据库管理系统、程序库、执行控制模块和9个独立的FORTRAN技术模块组成。每个模块计算部分提出的PAN AIR问题。数据库管理器用于模块之间和模块内部的通信。对于每个PAN AIR问题，必须以规定的方式运行技术模块。为了缓解提供执行模块所需的许多JCL卡的问题，创建了一组CRAY过程（PAPROCS）来自动提供大多数JCL卡。本文档的大部分内容在3.0版中没有更改。然而，它现在仅严格适用于PAN AIR 3.0版本。主要变化是：（1）包括新FDP模块（计算流线和离体点）的附加章节;（2）完全重写MAG模块章节;（3）严格适用于CRAY计算系统。
The Maintenance Document Version 3.0 is a guide to the PAN AIR software system, a system which computes the subsonic or supersonic linear potential flow about a body of nearly arbitrary shape, using a higher order panel method. The document describes the overall system and each program module of the system. Sufficient detail is given for program maintenance, updating, and modification. It is assumed that the reader is familiar with programming and CRAY computer systems. The PAN AIR system was written in FORTRAN 4 language except for a few CAL language subroutines which exist in the PAN AIR library. Structured programming techniques were used to provide code documentation and maintainability. The operating systems accommodated are COS 1.11, COS 1.12, COS 1.13, and COS 1.14 on the CRAY 1S, 1M, and X-MP computing systems. The system is comprised of a data base management system, a program library, an execution control module, and nine separate FORTRAN technical modules. Each module calculates part of the posed PAN AIR problem. The data base manager is used to communicate between modules and within modules. The technical modules must be run in a prescribed fashion for each PAN AIR problem. In order to ease the problem of supplying the many JCL cards required to execute the modules, a set of CRAY procedures (PAPROCS) was created to automatically supply most of the JCL cards. Most of this document has not changed for Version 3.0. It now, however, strictly applies only to PAN AIR version 3.0. The major changes are: (1) additional sections covering the new FDP module (which calculates streamlines and offbody points); (2) a complete rewrite of the section on the MAG module; and (3) strict applicability to CRAY computing systems.
