Dragan,

I am 100 % sure my code line work,

and for your coding:

*-- a dummy cursor, quite unimportant
create cursor zz (i i)

copy structure extended to dbfexte.dummy
close databases all
*-- if you want, quit VFP here, reload and run just these two lines:
use dbfexte.dummy    &&  howcan you never created dbfexte so your 'bang" is justified 
&&  the best thing would be a quesiton from VFP which codetable you intend to use for dbfecte.dummy  
*-- bang, your code is dead:
copy structure extended to dbfexte.bzy  &&your forgot to use    

Now if you are interested, just for the record's sake, I could zip a small programm which worked on my system

Regards,

Koen
