<br>multiple-dimension array to hold all the answers to all the questions, e.g.,

<br>

<br>     Const  nQuestions as Integer = 4

<br>     Const  nAnswersMax as Integer = 10

<br>     Dim Answers( nQuestions, nAnswersMax )

<br>

<br>and then just use an array index to get the answers for the selected 

<br>question?  If you need to get fancier, you might use a User Defined 

<br>Type (akin to Structures or Records in other programming languages, 

look it up in the E-Basic Help facility), perhaps using an array of your UDTs.

<br>

<br>To answer your initial question, if you study the Rte, RteCollection, 

<br>and related topics in the E-Basic Help, you just might devise a way 

<br>to manage *object* variables with arbitrary names from strings, but 

<br>still not manage ordinary variables.  Even then, I think it generally 

<br>best to adapt techniques according to the tools at hand, which brings 

me back to ordinary multiple-dimension arrays in VBA/E-Basic.

<br>>e.g.

<br>>Then after the question slide, I use an inline to run through the

<br>>However, since there is a different array for each question, I need 

<br>>a way to select the proper array, which hopefully doesn't involve me

<br>>Something like:

<br>>    If c.getAttrib("arrayName")(<wbr>Counter) = Stimulus.RESP then

<br>>    end if

<br>>next

<br>>

<br>>.. although the above obviously doesn't work in the current form. 

<br>>Does anyone know of a way to do this, i.e. use strings stored in
