Don't use the addressblock. Use the individual fields.
Depending on which case the addresses are saved in you can use a formatting
switch to apply the required case

Why does the address have to be in upper case for window envelopes? Upper
case is harder to read.

Good question Mr. Mayor, address in caps is a careover from work. In mailing
correspondences, we were instructed to use caps, no punctuation. It is time
to change. Thanks for the info and question.

If your ADDRESSBLOCK works OK, you should be able to use the character
format switch \*Upper, e.g.
use Alt-F9 to display field codes. Your Addressblock field will look
something roughly like the following (mine's obviously intended for use in
the U.K.):
{ ADDRESSBLOCK \f "<<_TITLE0_ >><<_FIRST0_>><< _LAST0_>><< _SUFFIX0_>>
<<_COMPANY_,
>><<_STREET1_
>><<_STREET2_
>><<_CITY_
>><<_STATE_
>><<_POSTAL_>><<
_COUNTRY_>>" \l 2057 \c 2 \e "United Kingdom" \d }
then type \*Upper before the }, giving you
{ ADDRESSBLOCK \f "<<_TITLE0_ >><<_FIRST0_>><< _LAST0_>><< _SUFFIX0_>>
<<_COMPANY_,
>><<_STREET1_
>><<_STREET2_
>><<_CITY_
>><<_STATE_
>><<_POSTAL_>><<
_COUNTRY_>>" \l 2057 \c 2 \e "United Kingdom" \d \*Upper }
But I have the same question as Graham - do you really need to use
uppercase? If it's a requirement of your postal service, that would be
useful to know.
