CPI-C Proc Dialog - Settings

Use the CPI-C Proc Dialog - Settings window to change the attributes of a CPI-C Proc Dialog.

Destination for CPI-C Proc Dialog

Use the Destination tab to specify the transaction program (TP) and logical unit (LU) you want to connect to.

Partner TP name
In the Partner TP name field, type the name of the transaction program (TP) you want to access on the remote host
Partner LU alias
From the Partner LU alias field, type the alias of the logical unit (LU) you want to connect to on the remote host. This is the LU through which the partner TP accesses the network.
Symbolic destination
In the Symbolic destination field, type the symbolic destination name of the partner you want to connect to. This symbolic destination name must be defined as an entry in your CPI-C side information.

If you specify a symbolic destination, you do not need to specify values in the following fields:

Userid
In the Userid field, type the user ID you want to use to access the remote system.
Password
In the Password field, type the password you want to use to access the remote system.
Security
From the Security combo box, specify the level of APPC conversation security to use (Same, Pgm, or None).
Mode
From the Mode combo box, specify the transmission mode to use for the session. This mode can be any mode defined in the local Communications Manager configuration. The default value is #INTER.
Sync level
From the Sync level combo box, specify the level of APPC synchronization to use for the conversation.
Return control
From the Return control combo box, specify when the local LU should return control to the VisualAge application following an attempt to open a connection.

Data Attributes tab for CPI-C Proc Dialog

Use the Data Attributes tab to specify program initialization parameters and data handling options for a CPIC conversation.

Code page
In the Code page field, type the character code page used by the remote system. The default code page is whatever the current code page is for the system you are developing your application on.
Buffer length
In the Buffer length field, type the size of the memory buffer VisualAge should allocate for the data sent to and received from the server. For a remote external function call, the buffer size must be at least as large as the total size of the record used by the function. The default value for this field is 1024.
Big endian
Select Big endian to specify you want the partner to use the bigEndian format. If you do not select Big endian, the partner uses littleEndian format.

Records tab for CPI-C Proc Dialog

Use the Records tab to specify the record that will be passed to the function on the server. When VisualAge calls the remote function, it can pass the program a record containing input and output fields. When the function completes, any output fields are filled in with the function's output values.

If the remote function does not require a record, you can leave this page blank.

Function language
Under Function language, select the type (C or COBOL) for the record to be passed.
File name
In the File name field, type the name of the C header file or COBOL copybook file declaring the data types or records used by the external function. To list the available files, select Find. To view the contents of a file, select View. When you have specified the file you want to use, select Parse.
Parse
Select Parse to have VisualAge read the C header file or COBOL copybook file and build a list of records. From the list, you can manually build the parameter list to use with the external function. The records (or potential parameters) appear in the Available list. The parameters you select appear on the external function part's public interface. Then, other parts can set or retrieve the values contained in the records.
Available records
The Available records list shows all of the record formats, or data types, defined in the file specified in the File to Parse field.

If you are working with a C External Function, for a C header file, these are all of the data types declared with typedef or struct. If you are working with a COBOL External Function, for a COBOL copybook file, these are the record formats declared by 01-level and 77-level declarations. The items specified in the PROCEDURE DIVISION USING statement or "ENTRY" statement should compose the list of the To be passed.

Parameter word size
Under Parameter word size, select the word size used for system dependent data types (16 bit or 32 bit). This setting is not available on UNIX systems.
