The program for Unix workstations exported on a cassette, written with tar. It can be retrieved by issuing the following command
% tar xvo
This creates a number of subdirectories example/, data/, macros/, export_source/, and bin/.
The directory example/ contains files that allow you to start playing with O. The directory data/ contains the data bases and necessary startup files. The directory macros/ contains a number of useful O macros that you can use as examples to create your own, personalised macros. The directory bin/ contains the program O and some related programs. The Stardent GS1000/2000 programs have names starting with gs_, the Stardent 1500 with dr_, the Evans & Sutherland ESV with es_, the Silicon Graphics with 4d_, and the Hewlett-Packard with hp_. The export_source/ directory contains programs to convert extrernal map formats to a standard one, skeletonising and averaging programs and a program swapbytes to convert Vax mappage maps sent to the workstation with ftp.
All workstation implementations make use of dials.
Add a new environment variable to your login shell file .cshrc
