file

Mount a menu whose button contents are defined in the text file <file>. The default file extension is TAB. The position of the new menu on the tablet is indicated by digitising three corners in response to the appropriate prompts from the program. The position of the menu should not conflict with any existing menu currently mounted.
 

r

Replace a menu already mounted.
 

i

The number of the menu to be replaced. Menus are numbered in the sequence that they are mounted. This can be checked by the STATUS 6 command. If this parameter is omitted, then the menu to be replaced should be indicated by digitising a position within it in response to the prompt: "Digitise the tablet menu to be replaced"
 

With no parameters mount a menu with empty buttons.
