I am using the fopen command but ran into some syntax
difficulty;

i read in the file name from a text file like this:

id = fopen('D:\Files.txt')
FileName = fgetl(id)

then i want to do something like this:
directory = 'D:\Input\'
fid = fopen(directory FileName) ---- just to show an example
or
fid = fopen('D:\Input\'FileName) --- but i think i am
missing something.  Any help would be nice!
