Retrieves the requested information:
Retrieves the 1- to 8-character code that invokes the current task.
Retrieves the task identifier assigned by the system. The task identifier is a unique sequence number stored in a binary fullword numeric field. At system startup, the system sets the identifier to zero; each time a task is executed, the system increments the identifier by one.
Retrieves the 1- to 8-character identifier of the logical terminal associated with the current task.
Retrieves the version of the current DC/UCF system. The version number is an integer in the range 0 through 9999 stored in a binary halfword numeric field.
Retrieves the 1- to 8-character identifier of the physical terminal associated with the current task.
Retrieves the 32-character identifier of each user signed on to the logical terminal associated with the current task. If no user is signed on, the system returns blank.
Retrieves the screen dimensions of the physical terminal associated with the current task. The screen size is returned in a field that is divided into two halfword fields: the first halfword contains the row, the second halfword contains the column. For example, a 24-line by 80-character screen is represented by a value of 24 in the first halfword and 80 in the second halfword. If the current task is not associated with a terminal, the system returns a null value of 0.
Specifies the location to which the system returns the requested task-related information.
A register that points to the field or the symbolic name of a user-defined field whose length is compatible with the length of the field containing the requested data.
