If the program has not been saved when it is locked, a dialog box will
appear to warn that "The current program must be saved before being
locked. Do you want to continue?" If you choose "Yes", the program will
be saved and locked; if you choose "No", the operation will be cancelled.
After the program is locked, the item "Lock Program" on the menu turns
into the item "Unlock Program", and the data of all the units in the
program cannot be modified. If the user changes the data, a dialog box
will appear to warn that "This program is locked by XXX.( XXX is the
current account. Refer to 3.2) It can't be edited before you unlock it."
Press "OK", and exit the dialog box.
