The user needs to be either at an INPUT, INPUT ARRAY, MENU, or PROMPT for you gather input. You've eliminated the two INPUTs, and I think arrows on a PROMPT might be tricky but you might try COMMAND KEY(UP) and COMMAND KEY(DOWN) from a MENU. I'm not where I can give you same code right now, but I've done stuff similar to this before. email if you need a more specific example. ================ Dennis J.
