Before using the Logical File Entries screen, define a custom service on the Service
Definition screen. If you are using ENSCRIBE files, enter the RECORD description for
the file into the DDL dictionary. If you are using NonStop SQL, enter table
registration information on the SQL Table Registration screen.
Field Descriptions The following paragraphs describe the fields on the Logical File Entries screen.
Service Name
Displays the name of the service from the Service Definition screen. You cannot enter
data into this field.
Description
Displays a brief description of the current service. You cannot enter data into this
field.
Logical File Name
For ENSCRIBE files, enter a unique logical file name for each DDL record to be
accessed by this service in the language you are using (COBOL85 or C). The logical
file name cannot be the same as the DDL record name.
For NonStop SQL tables, enter a unique host variable name for each SQL table object
to be used by this service. The host variable name can be the same as the SQL table
object name as long as the name has not already been used in the Logical File Name
column.
For both ENSCRIBE and NonStop SQL files, the logical file name cannot be the same
as any reference object or alias name used on the IPC Definition screen for this service.
DDL Record/Table Object Name
For ENSCRIBE files, enter the DDL record name for each entry in the Logical File
Name column. The record must already be entered in the DDL dictionary.
If you are using NonStop SQL tables, enter the table object name for each entry in the
Logical File Name column. The table object must already be registered on the SQL
Table Registration screen.
Open Mode
Enter the access mode for each ENSCRIBE file. The Pathmaker product ignores the
Open Mode field for NonStop SQL tables.
Valid open mode codes for ENSCRIBE files are I, O, IO, and EX:
I Read-only (input) access
O Write-only (output) access
IO Both read and write access
EX Sequential write access
This field has no default value; you must enter a value for each ENSCRIBE file.
