HOME^%ZIS: Reset Home Device IO Variables

Reference Type: Supported, Category: Device Handler, Integration Agreement: 10086

Description

This API sets the key IO variables to match the characteristics of the home device. The HOME^%ZIS API performs the same function as the obsolete CURRENT^%ZIS API. Developers have been advised that Kernel V. 8.0 is the last version of Kernel to support CURRENT^%ZIS.

HOME^%ZIS, beyond updating the set of variables for the home device, also updates the active right margin system setting for the home device, by executing ^%ZOSF("RM") based on the home device's IOM value.

 

Format

  HOME^$ZIS

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.
