hi chris,

the file search list is a Lisp string, and Maxima strings aren't
Lisp strings (they are symbols which begin with ampersand).
the workaround suggested by mario should work --
sconcat returns a Lisp string. dunno why it worked before.
at some point we should bite the bullet and implement
Maxima strings with Lisp strings instead of symbols.
it would be tedious, but not difficult (maybe).
all the best,
robert dodier
