Re: why the 16meg space size limit?

["Alexei Pytel" <pytel@xxxxxxxxxx>]

Teraspace addressing mode allows to have arrays, memory blocks etc to be
larger than 16MB.
So working memory for program can be much larger than 16MB.

For permanent storage you can keep data, for example, in database files or
stream files, which can be much larger.

*USRSPC object does have 16MB limit.
I am curious why it is so important to have *USRSPC in particular to be
larger than 16MB ?

The existence of the 16-Mb limit is (like DOS's 640Kb) of course the
death knell of the AS/400 architechture. It can only be removed by
the same kind of antics that plagued DOS. The one mistake you
cannot recover from is limitations of the number of 'address' bits.
