About invoke types

The value that you select for the invoke type of an invoke node determines the other generation properties that the invoke node possesses.

When you run the Generate Runtime Code wizard and it processes an invoke node, the wizard generates COBOL source code and control information to implement the invocation described in the invoke node.

Recall that every invoke node in a generation properties file that you view in the generation properties editor corresponds to an Invoke node in the associated flow file that you can view with the flow editor. The invoke node that you view in the generation properties editor has the same name as the corresponding Invoke node that you view in the flow editor and contains the generation properties for that Invoke node (see Flow nodes and invoke nodes in the generation properties editor).

When you set an invoke type for an invoke node (using the Invoke Type list box in the generation properties editor after selecting an invoke node in the Outline view) the selection of invoke types that are available for you to choose from depends on the Invoke type of the corresponding node in the associated flow file (which you can view in the flow editor). See Table 1:
