You can specify the input and output messages for your IMS mobile
service by importing one or more data structure
files (COBOL copybooks or PL/I includes) into your IMS Mobile project.
To import data structures:
- From the IMS Explorer Transaction Message Metadata Editor,
select Input messages in the navigation tree
and click Import data structure.
Tips:
- If you select a segment or any of the nodes below a segment before you click Import data structure, the wizard automatically
populates the specified segment as the target.
If the data structure has changed for an existing transaction message, you can
reimport the data structure file by clicking Import data structure. Existing custom data structure
names (aliases) and remarks are preserved if the 01 level structure remains unchanged. 
- Specify the location to import the data
structures from, and specify the file type.
- Click Browse to
select the data structure file that contains the COBOL copybooks or
PL/I includes to import.
Tip: If you are importing an application source file that references a COPY or INCLUDE
file, import from a local file system with both the application source file and the referenced file
in the same directory.
- If you import the data structures from z/OS, the data structure file does not have a file
extension. It takes the file type that is specified in 2.
- If you import the data structures from a local file system, a file with one of the following
extensions takes that file type as default:
- A COBOL copybook can have any of the following file name extensions: .cbl, .ccp, .cpy, or .cob.
- A PL/I include can have any of the following file name extensions: .pli, .inc, or .mac.
Tip: If the file extension is incorrect for the type of file type that the file is,
either change the file extension or click , and then select either COBOL or PL/I from the list on the left. Then, edit the type
of file that is indicated by each file extension.
If the data structure file does not have
a file extension, it takes the file type that is
specified in 2.
-
Select the data structure name and the associated message and segment to import the data
structure into.
- Click Add to Import List.
-
In the Import data structure wizard, select
Output messages in the navigation tree and click Import data structure.
- Repeat steps 3 through 5 for each data structure
that you want to import as an output message.
- Click Finish to import the fields
into the input or output message.
If you are updating an existing data structure, a dialog opens. Click
Yes to replace the existing data structure and preserve your aliases and
remarks. Click
No to add the data structure as a new, separate data
structure.
Tip: For each additional segment, click the Segments folder and
click
Add. Repeat the steps from step 3 for each data structure that you want
to import as input and output messages. For more information and restrictions, see
Adding segments to transaction messages.
