EGL Reference Guide for iSeries
With few exceptions, each logic, data, and user-interface part in EGL has a
set of properties, whether assigned or by default. The feature is used
widely in EGL:
- Properties are in effect when a record part or data item part is used as a
typedef (a model of format). The typedef might be for use by another
part, by a variable, or by a structure item that is used in a part or in a
variable. The part, structure item, or variable that uses another part
as a typedef can override the properties that are in the typedef.
- Properties are also in effect for parts of type dataTable, form,
formGroup, library, program, and pageHandler.
No overrides occur for form-level properties. If a property like
validationBypassKeys is specified in a form, for example, the value
in the form is in effect at run time. If a form-level property is not
specified in the form, however, the situation is as follows:
- EGL run time uses the value in the program's use declaration
- If no value is specified in the program's use declaration, EGL run
time uses the value (if any) in the form group
