You are correct. As others indicated with examples, there are applications that correctly have tens of thousands of open files. I should have been more clear to say that it is important to understand what the program is doing and why, when I composed my caution. There is clearly a case for extreme programming where extreme system params and configs are needed. The programmer and the user of that program should be aware of this. In fact the program should be aware and in the error condition exit messages and help screens give clear diagnostic messages and hints for tuning. On the converse much of what looks like extreme programming is lazy or more commonly prototype programming that has made it big. -- T o m M i t c h e l l Just say no to 74LS73 in 2004
