Operating Environment
Operating environments are named collections of environment settings that change the way in which Reality functions. For example, you might create an environment for backwards compatibility with an earlier version of Reality, or to simplify migration from a different type of MultiValue system. Several predefined environments are provided, which you can use either directly or as templates for creating your own environments.
Environments are maintained by using SSM Option 4 - Define Environment Settings (or the DEFINE-ENVIRONMENT TCL command) to access the ENVIRONMENT CONFIGURATION screen and are held in the ENVIRONMENT system file in the SYSFILES account.
It is recommended that you associate the environments you create with user profiles, so that each user is given a suitable profile at log on. In addition, an option in the user's security profile allows you specify the action to be taken if the environment specified for the user cannot be found or is invalid.
You can apply an environment when needed with the SET-ENVIRONMENT TCL command, and you can set and clear environment options with the SET-OPTION and CLEAR-OPTION commands respectively.
The options that are currently set can be listed with LIST CUSTOM.OPTIONS.
