Initial Requester
Enter Y or N to determine if the current requester is the first requester in the
Pathmaker application for one or more users.
Y Designates that the current requester is an initial requester.
N Designates that the current requester is not an initial requester. This is the default
setting.
If you view the application's set of navigation paths as a tree, an initial requester is the
root of the tree. A Pathway application can consist entirely of an application
developed using the Pathmaker product or can consist of a Pathmaker portion
contained within Pathway application code written outside of the Pathmaker product.
In either case, the initial requester is usually the first Pathmaker requester that you see.
You cannot call an initial requester from any other Pathmaker requester.
However, it is possible to have the first requester in an application compiled outside of
the Pathmaker product. In this case, the requester must be registered. A registered
(REG) requester is the only type of requester that can call a Pathmaker initial
requester.
A single project can have any number of initial requesters. If you have a mixture of
terminal types, you need separate sets of requesters for 3270 and 6520/6530 terminals,
although both sets can send to the same servers. You can use different initial
requesters in this case to create separate entry points for different terminals.
You can create an initial requester either with or without formal parameters. An initial
requester without formal parameters might be the first requester for the entire
application; therefore, the Pathmaker product creates a PROGRAM entry in the
Pathway configuration for this application for each initial requester without formal
parameters. In Pathway, PROGRAMs allow you to run your application from
nondedicated terminals.
An initial requester with formal parameters must be called by a requester coded
outside of the Pathmaker environment. You could, for example, code a logon screen
that calls the Pathmaker initial requester, passing security information with the call.
Requester Context
The fields under this heading give information about the reference objects of your
requester.
Single Reference Object
Use the Single Reference Object field to enter the name of a RECORD or DEFINITON
from the DDL description of your database or a NonStop SQL table object name from
the SQL Table Registration screen that you want to add to this requester. Adding a
RECORD, DEFINITION, or table object name here adds the record, definition, or table
as a reference object to this requester’s context. You can add reference objects to
TRNS, DB, and MENU requesters.
