\ in macro?

[Han-Wen Nienhuys]

Hi,

I have


        @macro refcommand{WHAT}
        @cindex @code{\WHAT\}
        @code{\WHAT\}
        @end macro


When I write

     @refcommand \arpeggio 

I get

        (lilypond.tmp) (lilypond.tmp) [146] (lilypond.tmp) (Index) [147] 
(lilypond.cps)

        Runaway argument?
        {\} \entry {\code {\xeatspaces {\arpeggio }}}{74} \entry {\code 
{\xeatspaces \E
        TC.
        ! File ended while scanning use of \initial.
        <inserted text> 
                        \par 
        \next ...\begindoublecolumns \input \jobname .#1s 
                                                          \enddoublecolumns \fi 
\fi ...
        l.14227 @printindex cp



how do I get a \ in an index entry using the macro system?
