It seems, that the tso-programmers reserved only 3 Bytes for this field. Normally the hex 0-7FF (are positive numbers) FFF-800 (are negative numbers).
But i dont know anybody who needs more than 512 MB. And this only for starting java applications in the own region.

Testing the changes I noticed when I log on to TSO the help panel says that the maximum possible region size is 2096128. This is 1 MB less than 2 GB, which would be 2097152. Can somebody tell me why the max is not exactly 2GB?
