Use the Text Editor

To use the text editor

From the TSO Ready prompt, enter ISH.
This starts the I Shell user interface to USS files.
Near the center of the screen, ISH displays an input area where you enter the USS path name for the HFS or zFS in compatibility mode directory containing the file you want to edit. For example:
```
/sys/usr/lpp/opsmvs
```
Leave the command line blank and press Enter.
The directory containing the desired file displays.
Scroll as needed using the PF7 and PF8 keys to find the file to edit
Enter a question mark (?) beside the file name and press Enter.
The pop-up box displays
Enter 5 in the pop-up box.
The editor initiates, which behaves like ISPF edit, and you can edit your file.
