9.17 Set

The `set` command modifies the default shell options. For example, `set +t` sets the `+t` option for all subsequent FunnelWeb runs within the shell until another set command sets `-t`.

    Syntax:
       set = "set" s ordinary_funnelweb_command_line
    Examples:
       set sloth +t +d
       set -lwalrus

The restrictions on the `set` command are identical to those on the `fw` command except that, in addition, the `+F` option cannot be turned on in the `set` command.

The set command is useful for setting option defaults before a long run of regression tests. It could also be useful to set default options in a FunnelWeb shell kept by a user in a workstation window.
