  - Templates
    FM/IMS uses templates to format database segments into their individual fields. One template is required for each database.
    - How static and dynamic templates are used
      How the static or dynamic template is used depends on whether the function requests a new or an existing view or criteria set.
    - View and criteria set usage rules
      - When the function generates a template
        The VCURUDT parameter specifies the usage rules that apply to views and criteria sets when the function generates a template for the database.
      - When the function does not generate a template
        The VCURULE parameter specifies the usage rules for views and criteria sets that apply when the function does not generate a template for the database.

View and criteria set usage rules

Usage rules specify whether a view or criteria set can be used with a database and, if it can, whether the function uses the view or criteria set specified by the user or a composite view or criteria set created by adding the view or criteria set’s selection information to the static or dynamic template.

When a composite view or composite criteria set is used, the template is used to format database segments into their individual fields. Otherwise, the view or criteria set is used to format database segments into their individual fields.

You can specify one set of rules for when the function generates a template for the database and another set of rules for when it doesn’t.
