Thanks Craig,

I have a program that I call in nearly every program I write, that defines about one hundred global variables, such as the date, time, working directory, default color table, etc., using the defsysv command. In any given program I'd use only a handful of these, but I wouldn't necessarily know which ones until the program was finished.

Based on David's books, it seems to me that using a common block in such a case would be a real pain.

Am I missing something as regards global variables?

Thanks,

Mark
