There are a selection of ways, it depends what you are doing.  Sometimes it
is appropriate to do

        string$equal ("clu", "CLU") cor string$equal ("clu", "clu")

Sometimes it is appropriate to convert to upper or lower case before
comparing, eg

        string$equal (supper ("clu"), "CLU")

The way ted does case-indepentent searches is interesting, it uses
_bytevec$nc_indexv and it makes use of _cvt [_bytevec, string]() which is
horrible :-)
