17.9 Case Example
The general operation of the file management is described below, using the "Program Editor" as
an example.
(1) Example A: Check out and Check in
① Check out a production program file:
Click-hold on the production program file “ProductionProgramA.iss” at the Program
Explorer area, and drag and drop it on the application area.
(* To “Check out” a file, the file has to be in the checked-in state.)
Figure 17.9-1 Before checking out (drag and drop a file)
Once you checked out the file, it is copied to the client PC, and Program Editor loads it
automatically.
Figure17.9-2 After checking out
* In this state, contents of the file “ProductionProgramA.iss” in the database and in a client PC
are the same.
(When you check out a production program file, if the client PC already has a file that has the
same name with a different date of update, a dialog message appears asking whether you
want to overwrite it or not.)
* Since the file “ProductionProgramA.iss” on the database has already been checked out,
you cannot check it out from the database.
② Edit the file “ProductionProgramA.iss” by the Program Editor and save it.
* Contents of the file “ProductionProgramA.iss” in the database and in a client PC are now
different.

③ Check in the production program file:
On the Program Explorer area, right-click on the file name “ProductionProgramA.iss” and
select the “Check in” from the pop-up menu. Contents of the file “ProductionProgramA.iss”,
which is edited on the client PC, are reflected to the file on the database.
Figure 17.9-3 After checking in
* Once the file that you edited is checked in, the file “ProductionProgramA.iss” in the database
is overwritten; contents of the file in the database and in the client PC become the same.
* The file “ProductionProgramA.iss” is now in the checked-in state; it can be checked out again.
(2) Example B: Difference between “Check out” and “Get”
① “Check out” a production program file :
Procedures are the same as ① of Example A; Click-hold on the production program file
“ProductionProgramA.iss” on the Program Explorer area, and drag and drop it on the
application area.
(* To “Check out” a file, the file has to be in the checked-in state.)
Once you checked out the file, it is copied to the client PC, and Program Editor loads it
automatically.
② “Get” a production program file :
Again drag and drop the same file “ProductionProgramA.iss”, which is currently in the
checked-out state; this operation is to “Get” the file.
(* To “Get” a file by the drag-and-drop operation, the file has to be in the checked-out state.)
Figure17.9-4 “Get” a production program file (drag and drop a file)
Every time when you “Get” a file, a message appears asking whether you want to “Get” the file
or not. Click <Yes> on the message box and specify a local path (location to store the file you
“Get”) on the client PC.
(During the check out operation, this message does NOT appear; once the location is specified
on a client PC, the system always uses the same location to have a checked-out file.)
The state of the file
changed; it has
been checked in.
