Exactly. However, there is no flow control outside of main(), so I don't account for variables declared outside of main(). If someone is declaring a variable in an area of the program with no flow control, then they are explicitly declaring their intentions that the variable will be global. In other words, it is not a surprise or a gotcha when the variable is available in a different scope. -- Dotan Cohen http://gibberish.co.il http://what-is-what.com -- You received this message from the "vim_use" maillist.
