SCOOPS and obsolete forms
Thanks to folks here in netland, I recently got a copy of SCOOPS
(for those still wondering where it can be found, try ftp to
linc.cis.upenn.edu (220.127.116.11). email@example.com
seems to be the responsible party, though don't take this as *my*
endorsement to hound him with mail.
In any case, I found two problems in bringing scoops up under
First, the replacements of "syntax-table-define ..." with "add-syntax!"
et. al were unnecessary - I didn't touch my existing runtime band.
Second, SCOOPS made use of the REC special form. This was apparently
removed from the language as of R3RS. In any case, I got runtime
errors (Unbound variable NAME). It is always used in the form:
((rec name (lambda ...)) args ...)
where name needs to recursively call itself. I'm no SCHEME wizard,
but it seemed the proper equivalent was:
(let ((name (lambda ...))) (name args ...))
which appears to run just fine.
Can anybody enlighten me on the subject of REC and its demise?
