visual program must be opened before it can be executed: #!N 
#!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N 1. From the Data 
Explorer Startup window choose  #!F-adobe-times-bold-r-normal--18*   Edit Visual Program #!EF . A 
file selection dialog box appears (see  #!Lfilesel3,dxall4 f Figure 3  #!EL  ). You can also 
get to the file selection dialog by choosing  #!F-adobe-times-bold-r-normal--18*   Run Visual 
Program #!EF in the Startup window or, once the visual program 
editor or image window has appeared, by selecting  #!F-adobe-times-bold-r-normal--18*   File #!EF 
in the menu bar of the window and then selecting  #!F-adobe-times-bold-r-normal--18*   
Open Program #!EF . #!N #!I30 #!N 2.  #!F-adobe-times-medium-i-normal--18*   Double click 
#!EF on any part of the  #!F-adobe-times-bold-r-normal--18*   Filter #!EF field at 
the top of the dialog box. Any text in that field 
will appear against the background of a black highlight bar. #!N 
#!I30 #!N 3. Type #!N #!N /usr/lpp/dx/samples/tutorial/*.net #!N #!N (The cursor 
automatically moves to the beginning of the text line as soon 
as you start typing, and the highlighted text and highlight bar 
disappear.) Note: The file extension .net (for network) is the default 
for Data Explorer visual programs. In Data Explorer, "network" is a 
term for visual program. #!N #!I30 #!N 4. Press  #!F-adobe-times-bold-r-normal--18*   Enter 
#!EF or click on the  #!F-adobe-times-bold-r-normal--18*   Filter #!EF pushbutton at the 
bottom of the dialog box. The  #!F-adobe-times-bold-r-normal--18*   Selection #!EF field just 
above this button now displays the directory path name. An alphabetized 
list of the .net files in the directory appears in the 
 #!F-adobe-times-bold-r-normal--18*   Files #!EF field. Note: If the path name you typed 
is invalid (the wrong list or no list of files appears), 
you can edit it: position the mouse cursor at the point 
where you want to start editing and click  #!F-adobe-times-medium-i-normal--18*   once #!EF 
before beginning to type. #!N #!N If the highlight bar reappears, 
retyping the entire path name is still unnecessary: again, position the 
cursor and click  #!F-adobe-times-medium-i-normal--18*   once #!EF . The highlight bar disappears, 
but the path name remains, with the cursor at the selected 
position. #!N #!I30 #!N 5. Use the scroll bar to move 
to the bottom of the list in the  #!F-adobe-times-bold-r-normal--18*   Files #!EF 
field. Click on example1.net to highlight the file name. The  #!F-adobe-times-bold-r-normal--18*   
Selection #!EF field now displays the file's full path name. #!N 
#!I30 #!N 6. Click on  #!F-adobe-times-bold-r-normal--18*   OK #!EF to open the 
example1.net visual program: the dialog box closes; a "network" of modules 
and connecting lines appears in the "canvas" area of the VPE 
window; and the full path name of the program appears in 
the title bar of the window. Opening is completed. #!N #!I0

#!N #!I30 #!N o It is not necessary to clear the

program. #!N #!I30 #!N o If for any reason you want

click on  #!F-adobe-times-bold-r-normal--18*   File #!EF in the menu bar and select 
 #!F-adobe-times-bold-r-normal--18*   New #!EF in the pull-down menu. This sequence clears the
