    int MapFunction( MapExpr )
      chain_list *MapExpr;
    {
      return( getabldepthexpr( MapExpr ) );
    }
    ...
    chain_list *Expr;
    chain_list *Expr1;
    Expr = createablbinexpr( ABL_AND, 
                             createablatom( "a" ),
                             createablatom( "b" ) );
   Expr1 = getablexprmax( MapFunction, Expr );
