This is my first post and I don’t know much about the micros system I have. It is 3700 Micros system and was purchased used. I need to set up a special prep button where the server can type in numbers and letters and this is attached to a previous entry. Currently the spec prep button generates a screen that asks for an amount. I can build a whole new button but don’t know what I am looking for to attach the needed screen with characters on it. I appreciate the help.
