I modified the shell to disallow changing an associative array to an indexed array. The other direction is legal and meaningful. The -A and -a attributes can be applied with -C to produce arrays of compound variables. > 3.

This already the case $ typeset +A z ksh: typeset: cannot unset attribute C or A or a David Korn [email protected] _______________________________________________ ast-users mailing list [email protected] https://mailman.research.att.com/mailman/listinfo/ast-users
