Thank you all for your encouragement. I need to think about the core functionality, and do some reading.

But what _is_ "the core functionality". The Single Unix Specification can be browsed on-line. There is no part of it labelled "core"; it's all required or it isn't AWK. There are weird little gotchas like File "foo" = '{ prin' File "bar" = 't 2 }' awk -f foo -f bar is legal and is required to act the same as awk '{ print 2 }' mawk fails this, and I don't blame it, and I don't really _care_. Is that "core"? Who knows? Whatever the "core functionality" might be, YOU will have to define what that "core" is. There's no standard, or even common, sublanguage.
