Hello,

I use ACL 3.0.1 on a pentium 90 with 48 Mb of Ram, and need help about memory 
management.

Basically I need to represent a mapping from the set of the n first positive integers
to itself, with n ~= (expt 10 6).

I have try with an hash-table and with an array, but I run out of memory.

Is the reason of this the size of symbols which appear to be bigs? Is there a way
to defined structures fitting exactly the space need of integers <= 10^6 ?

On the other hand: 

(room) =>  1,874,456 bytes free before next GC.
           462 garbage collections so far.
           Total GC time: 73.16 seconds (73160 clock ticks)
           Time since startup: 3452.93 seconds (3452928 clock ticks)
           Free heap space 1,910,716 bytes.

seems to indicate that more memory could be given to ACL.  Is it possible to calibrate
the memory useable by Lisp?

Thank you very much in advance for your replies.
Antoine Zahnd.
