   Hi,
   
   I would like to make some macros, which would simulate nested IF/ENDIF.
   
   So something like this:
   

   IF_AT book, table
        IF_AT glasses, yourself
          SAY read_book
          PROGRESS        
        END_IF
     END_IF
   

   
   
   To be able to nest the IF_AT, END_IF macros, I need some kind of stack. Maybe numbering labels would be enough (IF would increment number, ENDIF decrement).
   
   Did somebody do something like this using MADS? Any ideas?
   
   Thanks.
