Global Parameters
The formal parameters of the interface of a
function module can be made known globally by choosing
Edit ->
Interface - Globalize Parameters in Function Builder. Then the field
Global is selected in the properties of the function module. The
formal parameters of a global interface have the following properties:
All parameters that are fully typed and are defined for being passed as
a value are treated as if global data objects of the same name were
declared in the Top Include. This means they are visible in the same
function group and, when the function module is exited, they retain
their value.
All the other parameters are handled as if data objects of the same name
were declared in the top include (for
table parameters , two in each
case # one for the table body, one for the header line). But they can
only be used during execution of the function module. If a parameter of
this type is accessed when the function module is not executed, the
runtime error GETWA_NOT_ASSIGNED occurs, since these parameters
are realized internally by field symbols. A data object is only assigned
to these field symbols while the function module is being executed.
In the function group, no global data objects with the same name (such
as a global parameter) may be created. If multiple function modules in a
function group have global interfaces, similarly named parameters must
have identical definitions.
Note
The use of global interface parameters is obsolete and, in new function
modules, interfaces should generally not be globalized.
