SENDLIST.DYNAMIC (SLDYN)
When data is downloaded
When a SENDLIST.DYNAMIC; command is executed at runtime, your dynamic list box
data is prepared for downloading to PowerClient. This data:
$ Applies to data items with the LISTBOX; or LISTBOX*; Data Attribute
$ Is stored in the PowerClient repository, for use whenever the named list box is
required for a screen format
$ Is downloaded to PowerClient or NOF:
v At end of transaction
v When a SLEEP; or CRITICAL.POINT; command is executed in a Report initiated
from a PowerClient or NOF terminal
v On MCP based target hosts, when an Ispec in another Subsystem is recalled
For OS 2200 Based LINC Systems
For an OS 2200 based LINC System, move the transaction ID for WDP into GLB.STN before
executing the SENDLIST.DYNAMIC; command. In addition, you should note the following
consideration when using large dynamic listboxes.
Large dynamic listboxes
Large dynamic listboxes (greater than 2000 entries of 30 characters) on 2200 Series hosts
can cause severe network congestion. This may result in the PCE station not receiving all
the listbox information. If the information cannot be delivered, it is discarded by the
standard (non-LINC) host communications software.
To avoid network congestion, perform one of the following:
$ Make the listbox static (using the SENDLIST.STATIC; command)
$ Adjust the CMS1100 configuration parameter MAX-QUEUE-ENTRIES (default is 10).
This defines the maximum depth of messages that can be queued to a terminal before
the MCB discards the information. For the impact of changing this parameter, see your
Communications Management System (CMS 1100) Configuration Reference
Manual.
Format of the Data
The SENDLIST.DYNAMIC; command downloads a single alphanumeric value. This value
consists of a number of parts - referred to as columns - separated by delimiters.
How the various columns are used is determined by your PowerClient application. See
your PowerClient documentation for further details.
