Server #!N #!EC #!N #!N The function DXLSend (see  #!Lmsgrtns,dxall1150 h Messaging Routines  #!EL  ) 
sends specific messages directly to the server. In general, one needs 
to be sure that the server will either handle the message 
properly or ignore it. The user interface will ignore most unrecognized 
messages, while the executive will accept most legal scripting-language commands.  #!Lsetvars,dxall1154 h Setting Variables  #!EL  
discusses how an application program can set the value of variables 
in a visual program. #!N #!N Other functions may also result 
in messages to the server. For example, DXLStartDX initiates the connection 
to the server and manages all the messaging associated with establishing 
the connection to Data Explorer. #!N #!N When a function call 
results in sending a message to the server, DXLink can either 
synchronize with the server to ensure that the message has been 
accepted or it can return without receiving an acknowledgment. By default, 
DXLink is configured to use the latter (asynchronous) method. DXLSetSynchronous sets 
the synchronization method to be used. DXLSync allows synchronization at specified 
points in an application that does not use synchronous mode. #!N
