[Zope] Stupid DTML Question

[James W. Howe]

Is there a way in a DTML method to create a new variable, assigning it an 
initial value, and then change the value later?  Something like:

flag = false
if some condition
    flag = true

if flag
    do something
else
    do something else.

I know that I can create a variable using Let, but I don't see how I can 
change the value of that variable after it has been created.

Thanks.
