Specifying CALL and
SEND Parameters
After you have defined the requesters and coded the services for your application, you
must integrate the requesters and services. To perform this step, you must define any
parameters a requester will receive from another requester, define any parameters to
be passed from a requester to another requester, and define any parameters sent from
a requester to a service through an IPC message. You cannot integrate requesters and
services until all called requesters and all invoked services are defined.
To integrate requesters and services, you should have already performed the following
preliminary steps:
1. Created the DDL.
2. Registered the tables (if you are using NonStop SQL).
3. Created the requester.
4. Defined the function keys and their prompt text.
5. Enhanced the appearance of the screen using the Screen Painter (optional).
6. Created the services.
7. Coded the custom COBOL or C code.
8. Specified IPC messages.
9. Related the DDL record names to logical file names. If you are using
NonStop SQL, you should have specified host variable names at this step.
10. Specify requester parameters.
To complete integration, you should perform the following steps:
1. Specify CALL parameters.
2. Specify SEND parameters.
You can only specify CALL and SEND parameters after the requesters being called or
the services being invoked have been added to the project catalog and have had their
parameters defined.
After you have integrated requesters and services, you are ready to generate a fully
functioning version of the requester.
