Dear Alp,
I do not know what kind of study/trial you plan but here is just a cautionary note on using only blocks of 2:
If it is a randomized-controlled trial where participants are recruited sequentially it will be very difficult if not impossible to conceal the allocation: investigators will be able to know the next allocation in every other patients even before actually randomizing the participants.
But as said, I do not know the exact study design so it might be appropriate anyway.

Dear Sven,
With option osize(1) I've got what I need. When considered to 1040 patients it's easier to finish a study with 960 patients. With your help it's possible now.
Thank you for your help.
