I suspect it is considerably less than that, although it depends on the specific code being written. >> BTW: it is normally only 50 lines in Perl.

Not so. Every line = more labour for the developer = more cost and time. Every line = more places for bugs to exist = more cost and time. I find it sometimes helps to imagine extreme cases. Suppose somebody comes to you and says "Hi, I want you to develop a web scrapping application to run on my custom hardware." You look at the project specifications and realise that the hardware has no OS, no TCP/IP, no file manager, no compiler. So you have to quote the potential customer on writing all these layers of software, potentially tens of millions of lines of code. Even porting an existing OS to the new hardware is not an insignificant job. Think how much time and money it would take. On the other extreme, the client comes to you and asks the same thing, except the hardware is a stock-standard Linux-based PC. Your development environment already contains an operating system, a file manager, TCP/IP, compilers, frameworks... and wget. The work you need to do is potentially as little as writing down the command "man wget" on a slip of paper and pushing it across the table to your customer. As programming languages go, C is closer to the first extreme, C++ a little further away, Java further away still, because Java provides more capabilities already built-in that the C programmer has to create from scratch. For many tasks, Python provides even more capabilities, in a language that demands less syntax scaffolding to make things happen. Every line of code you don't have to write not only is a bug that just can't happen, but it also saves time and labour. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
