[REBOL] Processing files / Any AWK users?

From: greggirwin::mindspring::com at: 18-Nov-2001 20:29

If I'm processing a file, by lines, thus: foreach line read/lines/with file rec-sep [ It appears that foreach doesn't call read on each pass, but I thought I'd ask to see if anyone knows, for certain. I know you can modify the block that foreach uses and it will see the changes, but I wasn't sure what magic occurs in this scenario. The real question, I suppose, is: Should I cache the return value from 'read before using it with foreach, or is that unnecessary? As a side question, does anyone on the list use AWK or think that something like it (i.e. an auto-driven rule/action file processor) would be useful? --Gregg
