logic new: test; string new: s; scalar new: num;

actions new: button_action; actions new: select_action;

select_action tick_actions=" s = + [table label?] + ; parser parse: s ; num - 1 ; s float_format= = num ; table label: s; " ;

button_action tick_actions=" test and: ([table row?],[table column?]) true: select_action tick!; ; " ;
