ISQED^%ZTLOAD: Return Task Status

Reference Type: Supported, Category: TaskMan, Integration Agreement: 10063


This API returns whether a task is currently pending. Pending means that the task is scheduled, waiting for an I/O device, waiting for a volume set link, or waiting for a partition in memory. It also returns the DUZ of the task's creator and the time the task was scheduled to start.



Make sure to perform the following steps before calling this API:

  1. NEW all non-namespaced variables.

  2. Set all input variables.

  3. Call the API.

Input Variables


(required) Task number of the task to look up. The task must be currently defined on the volume set to be searched, or the lookup fails.


(optional) The volume set TaskMan should search for the task being looked up. If not passed, TaskMan searches the current volume set. Unlike ^%ZTLOAD's ZTCPU input variable, this one does not accept a second :-piece specifying the CPU. It only specifies a volume set to search.

Output Variables


ZTSK(0) is returned as follows:

  • 1—Task ZTSK is currently scheduled or waiting on volume set ZTCPU.

  • 0—Task ZTSK is not currently scheduled or waiting on volume set ZTCPU.

  • NULL ("")—The lookup was unsuccessful.

(sometimes returned) The error code, returned when some error condition prevented a successful lookup. The codes and their values are:

  • IT—The task number was not valid (0, negative, or non-numeric).

  • I—The task does not exist on the specified volume set.

  • IS—The volume set is not listed in the VOLUME SET file (#14.5).

  • LS—The link to that volume set is not available.

  • U—An unexpected error arose (e.g., disk full, protection, etc.).

(sometimes returned) The date and time the task was scheduled to start, in $HOROLOG format. It is returned only if ZTSK(0) equals zero (0) or 1.


(sometimes returned) Holds the DUZ of the user who created the task. It is returned only if ZTSK(0) equals zero (0) or 1.
