Juan,
I think it will be rather time consuming to rewrite CVI runtime engine and the libraries I am using.
I was hoping to find out how difficult it would be to port to labview 7.1. I am using mainly the user interface functions like tables, graphs, tab panels, and numeric and toggle controls. The only external interface is a serial port. The operating system I am migrating to will be Pocket PC 2003 and palm OS. Can you offer any other advice?
