Easy (I do it all the time). Create two (almost identical) commands

Java

static final Command pauseCommand = new Command("Pause", Command.ITEM, 1);
static final Command resumeCommand = new Command("Resume", Command.ITEM, 1);

In your startup code, add only the pause command to your displayable (canvas, form or whatever).

In your commandAction routine, have something like this:

Java

public void commandAction(Command cmd, Displayable disp) {
    if (cmd.equals(pauseCommand)) {
        disp.removeCommand(pauseCommand);
        disp.addCommand(resumeCommand);
        // whatever you do to pause
    } else if (cmd.equals(resumeCommand)) {
        disp.removeCommand(resumeCommand);
        disp.addCommand(pauseCommand);
        // whatever you do to resume
    }
}

Note that if you are really pausing the midlet, a resume command inside it won't be very useful!
