Task Storage Display (2 S)

Related Topics

The Task Storage Display screen (2.S) sequentially displays a list of the areas contained on a task’s storage chain(s). Areas are displayed in LIFO sequence based on your selection criteria. The default is all chains and allocated storage elements, but you may also choose to display elements on the freed chains, any individual chain, or any combination of chains. The default is also to display storage areas for the current task being executed, but you may select any other active task by entering a new USER TCA address or TASK NUMBER.

Access this screen by entering the letter S on the Debugging Facilities Menu (2) or by entering =2.S in the COMMAND field. You can also access this screen as described in Transferring Between Screens. The storage area display begins at the most recently GETMAINed area on the USER31 transaction chain (or your selected chain). Access an area directly by issuing the LOCATE address command. Scroll through the list using the UP, DOWN, TOP, and BOTTOM commands. Locate the first occurrence of a string on the currently selected chains by issuing the FIND command and subsequent occurrences with the RFIND command.You can then select an area for viewing and/or updating. Based on your session type (XPED, XPRT, XPSP), you will be transferred to the applicable Memory Display screen (2.2 or 9.2) to view and/or update the data.

Input Fields

SEL

Enter S to display/update a single area from the list on the Memory Display screen (2.2 or 9.2, based on Code Debug session type).

TCA ADDRESS

Address of the user TCA of the transaction you want to list storage chains for.

TASK NUMBER

The TASK number of the transaction you want to list storage chains for.

DSA SELECTION FIELDS

Select the DSA chain or chains you want to display. Areas will be displayed in LIFO order. The default is ALL allocated areas for all chains. You can also request that freed chains be displayed, or both allocated and freed chains for any combination of selected DSA chains.

Only freed areas still on the chains are available—not all areas freed anytime during the duration of the transaction.

When you list storage for a task other than your own, the chains may change between when the task storage list is displayed and when your selection entry is processed.

Output Fields

TYPE

The DSA chain that contains the area. These are U31 (USER31), U24 (USER24), C31 (CICS31), and C24 (CICS24). If an area is on the freed chain, it will be followed by an F.

STORAGE ADDRESS

The application program’s starting address for the area. (IBM “crumple zones” are not included.)

ELEMENT LENGTH

The length of the area available for application use. (Adjustments have been made for IBM “crumple zones”.)

ELEMENT DATA

The first 16 bytes of the areas are displayed in hex and character mode to make selection easier. If you need to view a larger part of the area or want to update it, first select it to transfer to the Memory Display screen (2.2 or 9.2, based on Code Debug session type). Depending on your authority and the type of area you selected, you can then view the area and possibly update it.
