Re^2: cgi question

i noticed those variable mistakes after posting. While loop: i only want the first line and pattern match the fist set of digits. I have removed print statement; obviously not applicable in a cgi script. The basic idea is open the first file, N_Stru*

/data/190_*
/data/191_* etc
[download]

match the numbers, then search the images folder for the number.gif. for each of the images, show these on a web page. printing them by $image which is linked the the <img src code.

If you plan to read only the first line, then you don't need a while loop. Actually, in your loop, $GU_web is assigned twice a value : the first set of digits, and then the second, on the next line, since your "last" statement is done AFTER the assignment (that is, if your file contains digits on several lines : see tlm's answer below to match the digits).
