Setting up an APPC conversation
To set up an APPC conversation, open the settings for the Proc Dialog part, then fill in the following fields on the Destination Information page of the notebook: 
Partner TP name 
The name of the transaction program you want to access on the remote host. 
Partner LU alias 
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. If you provide a value in the Fully qualified partner LU name field, this field is not necessary. 
Fully qualified partner LU name 
The fully qualified LU name of the remote LU you want to connect to. If you provide a value in the Partner LU alias field, this field is not necessary. 
You can also specify values in the optional security fields of the settings notebook. On the Destination page you can fill in the following fields: 
User ID 
The user ID required to access the remote system. 
Password 
The password required to access to remote system. 
Security type 
The level of APPC conversation security to use. The valid value constants are as follows: 
•	None (Default) 
•	Same 
•	Pgm 
Fill in the following fields on the Conversation page: 
Local TP name 
The name that identifies the local program to the network. If you do not provide a value in this field, VA Smalltalk automatically generates a unique name at run time. 
Local LU alias 
The local LU alias to use. The alias must be defined in your communications software configuration. The VA Smalltalk default value is the default value specified in your communications configuration. This field is used only when you specify a value in the Local TP name field. 
Mode 
The transmission mode to use for the session. This can be any mode defined in the local communications software configuration. The default value is #INTER. 
Sync level 
The level of APPC synchronization to use for the conversation. The valid value constants are as follows: 
•	None (Default) 
•	Confirm 
Return control 
Specifies when the local LU returns control to the VA Smalltalk application following an attempt to open a connection. The valid value constants are as follows: 
•	WhenSessionAllocated (Default) 
•	Immediate 
•	WhenSessionFree 
•	When ConwinnerAllocated 
•	WhenConvGroupAllocated 
Fill in the following fields on the Data Attributes page: 
Code page 
The character code page used by the remote system. The default code page is the current code page for the system. 
Buffer length 
The size of the memory buffer VA Smalltalk should allocate for the data sent to and received from the server. For a proc dialog, the buffer size must be at least as large as the total size of the record used by the remote program logic. 
The default value for this field is 1024. 
Big endian 
A check box that determines the byte order for integers sent to the partner. If checked, the partner uses a BigEndian format; otherwise the partner uses LittleEndian format.
