Infoprint XT provides executable files, sample files, and informational files in the z/OS UNIX directory structure. The directory structure also contains the operating system files that control the environment. Depending on the task, you might need to view or edit some of the files. This procedure shows one method of accessing a file from the ISPF shell:

1. Open the ISPF shell, as previously described.
2. If you want to edit the file, and the file requires superuser authority, enter su on the command line.
3. Move the cursor to the first of the four lines in the center of the panel. Then, enter the name of an existing file. For example:

   /etc/profile

4. Press Enter. The resulting action depends on the actions performed in the last shell session. The shell either presents a menu from which you can select options such as viewing or editing the file, or the shell opens the file.
