The CICS tasks have been divided into major categories corresponding to the different stages of implementing and running a CICS system.
In the navigation panel on the left, click on the right-pointing "twisty" to the left of a category or on the category itself to open the category.
When a category is open clicking on the downward-pointing "twisty" to the left of the category closes the category. A category is also closed if any other category is opened.
