## Resources List

| Resource Name | What You can do for this Resource |
| --- | --- |
| FILE | Retrieves or sets data set information. If you omit the file name, CEMT displays a list of all data sets. |
| PROGRAM | Retrieves or sets program information. If you omit the program name, CEMT displays a list of all programs. |
| QUEUE | Retrieves or sets transient data information. If you omit the destination name, CEMT displays a list of all transient data queues. |
| TASK | Retrieves or sets task information. If you omit the task identifier, CEMT displays a list of all active tasks. |
| TERMINAL | Retrieves or sets terminal information. If you omit the terminal-id, CEMT displays a list of all terminals. |
| TRANSACTION | Retrieves or sets transaction information. If you omit the trans-id, CEMT displays a list of all transactions. |
| ENABLED | Changes the status of the resource to ENABLED or DISABLED. |
| DISABLED | Disabling a resource is often a good way to get out of a processing loop. For example, if your terminal is tied up by a pseudo-conversational transaction that keeps restarting itself, simply disable the transaction from another terminal. |
| OPEN | Changes the status of a data set or queue to OPEN or CLOSED. A |
| CLOSED | data set must be closed before you can update it outside of the CICS environment. |
| NEWCOPY | Establishes a new copy of a program or mapset. You should issue CEMT SET PROGRAM(name) NEWCOPY each time you recompile or reassemble a program or mapset. |
| DPLSUBSET | Specifies that a program run in a local CICS region is restricted to the Distributed Link Program API subset. In this mode, a program isn’t allowed to issue any CICS commands that access a terminal, which is useful for testing business logic programs. |
| TRIGGER | Changes the trigger level for an ATI task associated with a transient data queue. |
| INSERVICE OUTSERVICE | Specifies whether or not the terminal is available for use. |
| PURGE | Cancels a running task: For SET TASK, cancels the task indicated |
| FORCEPURGE | by the task identifier; for SET TERMINAL, cancels the task associated with the terminal. PURGE cancels the task only if CICS can ensure system and data integrity; FORCEPURGE cancels a task without regard to integrity. Always try PURGE first. |
| PAGEABLE | Specifies how a terminal handles multiple page messages. If |
| AUTOPAGEABLE | PAGEABLE is specified, the operator must retrieve message pages with the CSPG transaction; if AUTOPAGEABLE is specified, message pages are delivered one after another. PAGEABLE is usually specified for display devices, and AUTOPAGEABLE is usually specified for printer devices. |
| ATI | ATI means that the terminal can be used for transactions that are |
| NOATI | invoked via Automatic Transaction Initiation (ATI) facilities or for Intersystem Communication (ISC) transactions. NOATI means that the terminal can not be used for those transactions. |
| SHUTDOWN | Terminates the CICS system. |
| IMMEDIATE | Specifies that CICS should be terminated immediately, even if there are tasks still running. If you omit IMMEDIATE, CICS waits until any active tasks are completed. |
