<p>A system for editing a sequence control program is disclosed, which simplifies the operations required to edit subprograms. A main program and several subprograms, to each of which an identifier is affixed, are entered via a keyboard (1), and then stored in a memory (2) which serves as program storage means. When a command is entered via the keyboard (1) to display the identifiers, identifier reading means (3) selectively reads the identifiers from the memory (2), and display control means (5) then lists up the read identifiers on a monitor screen (6). In response to a selection command entered via the keyboard (1) to select one of such identifiers displayed on the screen, program reading means (4) reads out a program having the selected identifier from the memory (2) and displays it on the monitor screen (6) via the display control means (5). <IMAGE></p> |
