The Select(selector, tab) command is similar to the select function.  The boolean valued procedure, selector, is called on each element in tab.  A new table is returned containing only those elements of tab for which selector returns true.

The selector parameter is a procedure that accepts two arguments. The first argument is the encoded name (see EncodeName) of the procedure and the second is the rtable containing the profiling data.

selector := proc(n,t)
    # check the total number of function calls
    if (t[1][1] > 5) then
        return true;
    else
    return false;
    end if;
end proc;

a := proc( )
    return 1;
end proc;

b := proc( )
    local i;
    for i from 1 to 10 do
        a();
    end do;
end proc;
