To Service
Displays the name of the invokable service from the previous screen. You cannot
enter data into this field.
SEND or RECV
Displays SEND if the parameter is to be part of the request.
Displays RECV if the parameter is to be part of the reply.
Requester Reference Field
Enter text in this column to describe each parameter for the reference object.
If the parameter is to be sent as part of a request, enter a field within a reference
object that will be sent to the service parameter shown.
If the parameter is to be sent as part of a reply, enter a field within a reference
object that will receive the service parameter shown.
If a whole reference object is being sent to or received from a service, enter only
that reference object name.
To view information for reference objects, press F9 for a Reference Field Value List.
If you are using NonStop SQL, you can send either a single column value or a whole
row from a table. To send a whole row from a table, enter the table name. To send
only a single column to a service, create an ENSCRIBE DDL definition that matches
the length and type of the NonStop SQL column and enter this name in the IPC
Definition screen for the service. Then match the column name to the DDL definition
on the SEND Parameter Definition screen. The column name must be qualified by the
table name:
TABLE_OBJECT_NAME.COLUMN_NAME
The Pathmaker product supplies the reference object name if an exact match (exact
name, type, and length) with the TO or FROM field is found in the context of this
requester.
You can specify a pseudofield in the SEND or RECV fields. All pseudofield names in
the Pathmaker product begin with the symbol @. The following pseudofields can be
sent to a service:
@ADVISORY Displays an informational message from the application.
@CURRENT-PAGE Displays the page number in the screen for the current
requester.
@CURSOR-POSITION Sends information at the cursor position to a service.
