   What does the '0' do in this command? ... I should be able to figure this out, but I am stumped at the moment It is prompting the user for an "E" value, then storing it in E and then....
   
   

   Code (Text):

   Request "E=",E,0

   The manual should say.
   
   Executing the code might offer insight.
   
   
   But if I had to guess, I would say that it would use 0 as a default value. (e.g. if the user hit enter without typing in any data)

   Yeah, the manual is pretty terrible (i.e. wrong a lot of the time). I did figure this out though by trial and error. 0 turns alpha lock off, so that by default the user is entering a number and not a string.
