why would I need to change the size to a different structure type?
I double checked the example and this was in there, I just missed it.
I'll give it a try and see what happens... thanks!

This came directly out of the API document. BUT - I know this doesn't
work. The prototype for algControl doesn't have a fourth argument (the
params)...
While I like all the documentation that Ti gives us - it would be better
if they were correct. The doc is SPRUFE4 pages 60-61 is where the
examples are.
