This document establishes the basis for collaborative writing of transportable computer programs for x-ray crystallography. The concepts and general-purpose utility subroutines described here can be readily adapted to other scientific calculations. The complete system of crystallographic programs and subroutines is called XTAL and replaces the XRAY (6,7,8) system of programs. The coding language for the XTAL system is RATMAC (5).The XTAL system of programs contains routines for controlling execution of application programs. In this sense it forms a suboperating system that presents the same computational environment to the user and programmer irrespective of the operating system in use at a particular installation. These control routines replace all FORTRAN I/O code, supply character reading and writing, supply binary file reading and writing, serve as a support library for applications programs, and provide for interprogram communication.The XTAL system of crystallographic programs is based upon the XRAY program system. Although every attempt is made to test each program of the XTAL system, no warranty, expressed or implied, is made by the authors or their institutions as to the accuracy and functioning of the XTAL system, its subprograms, related program material, or operating instructions. No responsibility is assumed by the authors in connection with the use, attempted use, or applications of these programs.It would be appreciated if acknowledgment of the U3e of XTAL be made in published work. iv Programmer's Manual

Advantages in adopting RATMAC as the distribution and implementation language of the XTAL system have already been reported .…”

Program systems are used extensively for crystallographic computing. Most existing systems have problems with language incompatibility, computational inefficiency and poor adaptability. This is because many desirable features demand opposing strategies in system design. Systems development is also complicated by the increasing number of computer types and sizes capable of doing crystallographic calculations. This, coupled with the widening aspirations of crystallographers, is making the task of developing an efficient and comprehensive program system increasingly difficult, particularly with conventional Fortran programming methods. The XTAL system is being developed with a different approach to these problems. The distribution of XTAL source code is in the RATMAC preprocessor language, the use of efficient machine-specific code is encouraged, and a much more flexible directory-type file structure is used for archive data files.
