User defined touch-button menu (Softkeys)

[Gene222]

I can't get this program to work properly in RPN mode. Currently, using the program in the previous post (in RPN mode), to take the sin of 45 degrees you have to press: 45 [Enter] [Vars] SIN [Enter]. This key sequence puts 45 in the first stack register. The program then takes the 45 and changes it to 0.7071.

I tried to program the first [Enter] using RETURN(30); as shown in the program below. The program puts 45 in the first stack register, but then stops execution, which is what one would expect from the RETURN command. I don't know how to make the program continue execution.

RPN code that does not work

PHP Code:

KEY K_Vars()
BEGIN
  LOCAL ch_num,ch_items,func_list;
  // choose items
  ch_items:={"SIN","ASIN","COSH","ACOSH"};
  // function list
  func_list:={"SIN()","ASIN()","COSH()","ACOSH()"};
  RETURN(30);
  CHOOSE(ch_num,"Functions Menu",ch_items);
  RETURN(func_list(ch_num));
END;
