#!CNavyBlue #!N  #!Rconserv Connecting 
to the Server #!N #!EC #!N #!N Before you can execute 
a visual program, your workstation must have established connection to the 
server. When you start Data Explorer, the program automatically starts the 
server connection, unless you specified that only the user interface was 
to be started. However, if for some reason your workstation becomes 
disconnected between the time you start Data Explorer and the time 
you are ready to run a program, you must reestablish connection 
with the server. #!N #!N To start the server connection, select 
the  #!F-adobe-times-bold-r-normal--18*   Start Server... #!EF option from the  #!F-adobe-times-bold-r-normal--18*   Connection #!EF 
pull-down menus in the VPE or Image window. A dialog box 
appears (  #!Lservcon100,dxall493 f Figure 100  #!EL  ). #!Cbrown #!N  #!F-adobe-times-medium-r-normal--18*    #!Rservcon100 #!N Graphics omitted

Start Server Dialog Box #!EF #!N #!EC #!N #!N The Hostname 
field, by default, contains the name "localhost." If the DXHOST environment 
variable or the  #!F-adobe-times-bold-r-normal--18*   -host #!EF argument was specified, this field 
contains the setting of that variable. #!N #!N You can change 
the Hostname field by clicking on it and typing in the 
new name. When it displays the desired name, connect to the 
server by clicking on the  #!F-adobe-times-bold-r-normal--18*   Connect #!EF button. #!N #!N 
To change the options associated with starting the server, click on 
the Options... button. This opens the  #!F-adobe-times-bold-r-normal--18*   Options... #!EF dialog box 
(  #!Lservopt101,dxall493 f Figure 101  #!EL  ). Most of the time, it is not necessary 
to use these options. #!Cbrown #!N  #!F-adobe-times-medium-r-normal--18*    #!Rservopt101 #!N #!N Graphics

#!N  #!F-adobe-times-bold-r-normal--18*   Executive #!EF #!I50 #!N Specifies the name of the 
executive to run. You might change this field if you want 
to run a customized version of Data Explorer. #!N #!I0 #!N 
 #!F-adobe-times-bold-r-normal--18*   Working Directory #!EF #!I50 #!N Specifies the default directory to 
search for files. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Memory Size #!EF #!I50

#!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Options #!EF #!I50 #!N Specify options in this 
text box as you would on the command line when invoking 
Data Explorer; that is, each option must be preceded by a 
dash. #!N #!N  #!F-adobe-times-bold-r-normal--18*   -cache on #!EF saves the state of 
the visual program in memory after an execution. If the visual 
program changes, Data Explorer reexecutes only the portion of the program 
affected by the change. If  #!F-adobe-times-bold-r-normal--18*   -cache off #!EF is specified, 
Data Explorer must reexecute the entire program for each change. (The 
default setting is on.) #!N #!N  #!F-adobe-times-bold-r-normal--18*   -trace on #!EF displays 
each execution step, as it happens, in the  #!F-adobe-times-bold-r-normal--18*   Debug #!EF 
window. It is mainly used for debugging purposes. (The default setting 
is off.) #!N #!N  #!F-adobe-times-bold-r-normal--18*   -log on #!EF saves all communication 
between the server and the user interface to a file. (The 
default setting is off.) #!N #!N Other options are listed in

to a debugging session for a customized version of the Data 
Explorer executable. You can specify the port number in using the 
stepper below the button. Note that when this button is toggled 
on, all other fields in this dialog box become disabled. #!I0
