ENS^%ZISS: Set Up Screen Handling Variables

Reference Type: Supported, Category: Device Handler, Integration Agreement: 10088

Description

This API is used for screen management. This API sets up screen handling variables and other terminal type attributes.

Format

  ENS^%ZISS

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

  1. NEW all of the following variables.

  2. Set the input variables you want changed.

  3. Call the API.

If you do not follow these steps, the variables could unintentionally assume the values of the variables of the current running task.

Input Variables

IOST(0):

(required) Internal entry number of the selected device's subtype as recorded in the TERMINAL TYPE file (#3.2).
%ZIS:

(optional) If you define %ZIS = "I", the output array IOIS (mapping escape codes sent by input keys to input keys) is created.

NOTE: For a description of the IOIS nodes created, please refer to the Outputs that follow.

Output Variables

The output variables are listed below.

NOTE: Not all characteristics are possible on all terminal types. Also note that two of the variables are used with indirection, ioefld and iostbm (marked with * below). Furthermore, iostbm requires the setting of iotm and iobm as input variables for the top and bottom margins.
