here's a complete macro (still not the suggested syntax...)

; generalized from ToggleList, for any boolean mode
store-procedure ToggleMode mode='Mode'
        ~local %mode
        setv %mode &cat '$' $1
        ~if &or \
                &seq "TRUE" &indirect %mode \
                &seq "FALSE" &indirect %mode
                setv &indirect $1 &not &indirect %mode
        ~else
                write-message "Not a boolean mode"
        ~endif
~endm
