Input is entirely command driven, allowing unattended batch operation; a built-in Macro programming language allows the construction of a simple new 'command' that can execute other commands in a complex manner. Users store their own previously written macros in a macro libraries (a single disk file), and there is an extensive 'permanent' macro library available for all users.

History

In the 1970s Hughes Aircraft

 Company acquired the software code ACCOS-V and extensively upgraded it while maintaining the command structure: entry consists of a command word (case insensitive) up to six letters long, followed by an optional qualifier word up to eight letters long, then either a text field or a numeric field containing up to five numbers. The new code was named HEXAGON and many optical designers used interactive terminals to run the program on an IBM 4341 mainframe computer. In the 1980s the program expanded its capabilities in optimization, tolerance analysis, and physical optics; this later capability is a subset of HEXAGON named SOQ, for System Optical Quality, that models coherent laser systems using a two-dimensional complex field array. In the 1985 Hughes was sold to General Motors
