I should have remembered the 14-bit max, I used to work with 3270 datastreams extensivly long ago and far, far away. Never did get to work with 16-bit streams or partitions though.
Many thanks for the enlightenment.

I thought I had read here and elsewhere >that there is a limitation of 8192 on the total buffer size? Not so? Time to crack open the 3270 manuals, Peter! There are three kinds of addressing: 12-bit (max 4K buffer), 14-bit (max 16K buffer), and 16-bit (max 64K buffer). Applications can do 12- and 14-bit without batting an eye since the address formats are self-describing.16-bit requires only slightly more work. Maximum buffer sizes notwithstanding, the maximum number of rows is 255. The maximum number of columns is 255. The limiting factor here is ISPF -- not 3270, not TSO, not some myth regarding arbitrary screen dimension limits: http://bama.ua.edu/cgi-bin/wa?A2=ind0501&L=ibm-main&P=R45606 _ This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
