Problem with INPUT instruction on CAS Program

[compsystems]

HELLO, resuming programming in prime, I can not initiate a data entry box, ¿why?

PHP Code:

#cas
  p4_input_data()
  begin    
    local a; 
    input( a ); 
    return a;
  end;
#end 


OR

PHP Code:

#cas
  p4_input_data()
  BEGIN
    LOCAL a; 
    INPUT( a ); 
    RETURN(a);
  END;
#end

Will this work for you:

PHP Code:

EXPORT temp()
begin
 local x;
 input(x);
 return x;
end;

#cas
p4_input_data():=
BEGIN
 local a;
 a:=temp()
 return(a);
END;
#end
