The UnProfile() command stops collecting profiling data for all named procedures.

The UnProfile(proc1, proc2, ...) command stops collecting profiling data for the specified procedures.

The UnProfile function does not effect a procedure that is not currently being profiled.

Turning off profiling deletes the internal rtable that stores the profiling data for a procedure.  This rtable can be obtained by using the GetProfileTable function before calling UnProfile.  The Profile function accepts an rtable along with the procedure to reset the internal rtable.

a := proc(x)
    if (x > 1) then
        return 1;
    else
        return 0;
    end if;
end proc:
