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:
