Yes, I mean a single variable can address only 16MB of storage.

Which is why you and I both write wrapper service programs. Hide all the
details away. The trick is getting anyone to use it.

Alan,

Doing all the memory allocation and making a "manual array" (i.e. not
using DIM() but using BASED() and manually setting elements via pointer
math) may seem simple to you (and it does to me as well) but it is not
within the skill set of most RPG programmers.

If RPG can support a large enough array with the standard DIM() keyword,
then I don't see why you'd want to do it this way??

Also, when you say 'RPG can only address 16MB of storage', I hope you
actually meant that a single variable can only use 16MB of storage, and not
that you really think RPG can only address that much storage?!?!

Also, the OP said he needed 50 records of 400 bytes in size... so all of
this is purely us chatting... nothing anywhere near 16mb is called for
here.

so easy to circumvent that it really means nothing.

1. *TERASPACE the program.
2. Create a data structure based on a pointer.
3. Dynamically extend the array. (A new lines of code).
4. Use QSORT to sort it.
5. Read it back out via pointer.

It would be easy enough to make my XVSRTQ a teraspaced program instead of
using a user space for storage but as far as I know no one as every used
my
Dynamic Sort API. Only issues I have seen there is mixing models.

Good point Scott. I’m fairly certain that the 16Mb still applies. I’ll

do
some checking.

Jon,

Is this true even if you use STGMDL(*TERASPACE)?

Arrays are now only limited by the 16Mb single item storage limit (as

of V6). That also means that dynamic arrays can’t get you a bigger

array
unless you use terraspace.

Size limit is 16Mb / %Size(arratElement) - no hard limit.
