How to run G98 on AIX4.2

 I untarred G98 to a system AIX 4.2 installed. Unfortunately, I don't
 understand UNIX deeply for I haven't use UNIX systematically before.
 My problem is how to run my G98 jobs on this system. G98 was installed
 in the directory of /usr/g98, and my home directory is /home/ybfan.
 Thank you very much.
