Making this transition will be easy if you were really good when you  
coded originally - if not (we had to convert some tafs written back in  
the old .qry days...) then some code cleanup might be required to make  
things work. Quoting EVERYTHING often solves nagging problems - just a  
heads up...  Another good area to check is qualifying everything  
thoroughly - e.g., I now write

<@assign name='request$varname' value='<@left str="<@var  
request$othervar>" numchars="2">'>
rather than the old, quicker (and sloppier)

<@assign @@request$varname <@left @@request$othervar 2>>

MUCH safer...

This will be especially critical if you are planning a transition to  
J2EE with Witango.

For us it wasnt all that tedious moving from tango2000 to witango 5.

the biggest problem was that like Wayne said, unscoped variables would  
be in
the request (local) scope instead of the user scope by default.

You can change this behaviour in your witango.ini to make the default  
scope
user and that clears up your problems there.

It is good practice though to scope your variables.  Different scopes  
act
differently so it makes sense to be very specific about how you want  
your
variable to act by defining the scope.

You may hear things about the "request" scope, but request and local  
are one
and the same so thats nothing to worry about (:

we had a very nice and simple move over and things are running better  
than
ever ever since.

I want to upgrade from Tango2000 to Witango. Can I port the code
that is currently running in Tango2000 without any alternation to
Witango.


The major difference between T2000 and WT5 code is that the default  
VAR
SCOPE is USER in T2000 and REQUEST (or LOCAL) in WT5.

Any code you have written that doesn't stipulate SCOPE will be  
effected.

There may be other differences with regards to datasources and paths,  
but
as
you haven't specified I can't comment.

Basically you can do it but it will probably be a tedious job. One I  
am
currently about to embark upon.
