I am passing a variable in my link called, course_no=243. This variable will change depending on the link selected. In the script, I want to open a couple of files corresponding to the course number. For example, if course_no=243 then I want to open 243desc.txt and 243links.txt. If the link for 244 were selected, then I would open the corresponding files.

In my script, I'm opening the files using the following code: 

open (DESCDOC, "/usr/local/apache2/htdocs/crs_desc/$course_no . desc\.
+txt") || &problem;
my @descdoc = <DESCDOC>;
close DESCDOC;

As you can see, I want to append to the course number the rest of the file name so it will access the appropriate file. I can't seem to get the proper syntax to open the file. I've tried numerous combinations of concantenations but nothing works. The problem sub just displays a message to let me know the file didn't open. How should I write the open command?
Thanks.
Chris
