Making an option set current

To make an option set current, place an S in the Select column next to the option set name. You can create a new option set and make it current at the same time by placing an S next to the option set name you specify on the input line and then pressing ENTER. The option set you select becomes the current option set.

If automatic customization is active, and you select an option set other than the recommended option set, customization is de-activated. To re-activate automatic customization, you must make the recommended option set current.
