thanks much for the replies. every time i think i got something, i run into more questions. i've run across 'evaluating' and 'non evaluating' versions of functions. not just in this list but also in reading materials. i haven't experienced the difference between the two yet. in any case, i guess i'll just have to grow into it. think and program in the language more. even tho it would be slow. :) best /e -- UNSUBSCRIBE: mailto:[email protected]?subject=Unsubscribe
