Matlab => DDE HELP please

[gmrickards]

I am having a problem making a hotlink between Matlab and Paragon. I want my program to run continuously and right now I am doing that using an infinite loop. In my program I first use ddeinit to initate the conversation (which works), next is the loop which contains ddereq to request information and then ddeadv to set up the hotlink. However, I am not sure if I need to use ddereq at all or even where. I also don't know if I need to have these commands in a loop if ddeadv should update the information when it changes. Any help would be appreciated. Thank you!!
