I've got a few questions which perhaps some folks out there know answers to.
They are:
1. Using DOMAIN Pascal, if I allocate some storage with the new
function, then allocate some more with
RWS_$ALLOC_HEAP_POOL(RWS_$STD_POOL, <size>), do these calls
allocate the storage from the same area?
2. Assuming I am running a process on a DN3000 with 20 megabytes free
on it's local disk, but the process I am running is allocating 40
megabytes of storage, where does the process do it's paging to?
3. What's the size limit (if any) of the RWS_$GLOBAL_POOL?
Any help with these will be greatly appreciated.
Thankx in advance,
Bruce Thompson

Sort of. Pascal allocates chunks from the standard RWS pool and then
maintains a free list of its own.

If you actually touched all 40 megabytes of storage, you would get a disk
full exception. Can't manufacture something out of nothing. There is no
reserved "swap space".
3. What's the size limit (if any) of the RWS_$GLOBAL_POOL?
It depends on the size of the virtual address space on the machine your
running. On the 3000 there's about 7 MB of user-space accessible global
address space. The global libraries live there too. I took a quick look
and it seems that on my 3000 I have about 3MB left in that area.
