Exactly that I figured. Except that I'm still confusing & and + as in VFP.

Thanks again.

BTW, do you know, how much does each function cost? For instance, I showed my manager the following code, suggested at the forum:

=========

<%@ Language="VBScript" %>
<% Option Explicit %>
<%
'''''''''''
'UNIQUE ID'
'''''''''''
mvar = Trim(Cstr(Month(Now)))
dvar = Trim(Cstr(Day(Now)))
IF Len(mvar) = 1 THEN
    mvar = "0" & mvar
END IF
IF Len(dvar) = 1 THEN
    dvar = "0" & dvar
END IF
ui = Right(Cstr(Session.SessionID),3) & Year(Now) & mvar & dvar & Timer
%>

Your unique id is now stored in the VBScript variable ui. I like to use the Timer property. This is the amount of seconds, to the 100th of a second, that has elasped since midnight. Makes duplicating this ID virtually impossible since it also include the last 3 digits of the Session ID.

===========================
His comments were - 1) no need for trim, 2) doing cast operation is costly

So, it would be interesting to know the "weight" of each operation...

Can you comment?

Thanks.
