50g

thanks for the info !

local variables vs. global variables.... what a concept....very simple when explained.

Peculiar, I have spent the past couple of hours performing searches for a similar reference in the 50g user guide, advanced user manual, and users manual and have not been able to find anything.

I'm sure there is a logical extension of the info you provided with regard to the 50g SD memory card; however, it would be nice to see the rules/requirements in writing.
