SIGNUP FILE ought to be an indexed file. Sadly, CMS does not support
indexed files, but it becomes more and more apparent that this is what
LISTSERV needs. If I implement indexed files some day, this file will
probably be one of the first to be converted. Arbitrary string searches
(a la EXECIO LOCATE) would no longer be reasonably feasible in REXX: you
would have to read the file sequentially and use POS() on each record.
Key searches would of course be considerably faster.
Then there is the privacy issue. A user might be in the SIGNUP FILE
because he subscribed to a mailing list with the CONCEAL option. If you
were to install /WHOIS in (say) Germany, you would be breaking a couple
laws and could end up being sued.
