ok I got a new problem after the Dbl Link list was solve.
The moving from one node to another and back works perfectly.
now the problem is the information retrieve from the file.
for example, after I retrieve information form the file into the node when I ask to display the information in the node I got an a bunch of wierd text and the system bleeping.
however, it only applies to string type. I tried the same returning an integer and displaying on screen and it works fine.
then I tried setting the string (say fName) to another string and return it, it works fine.
It only Happens when I try to access the fName, a string, which obtian its information from a file.
