@macro

[prasanna]

Hello,
         I have a doubt, i am using the @macro command as below, but 
somehow it doesn't  work as i expect, i don't know if i am doing something 
wrong.
@macro TITLE
@b{
@end macro

@macro ENDTITLE
}
@end macro

Now what i want is, if i mention @TITLE it must substitute "  @b{  " and in 
the place of @ENDTITLE it must put
" } "

In future i want to change my title to italics i can just change the macro. 
But somehow this doesn't work.
can u suggest me something.
thanks and regards
prasanna
