A new version of the HASH package is released (on <LISPUSERS> and <NETLISP>).
It provides the following new features:
1. A new value-type, 2NUMBERS. The values of this type consist of
a cons cell whose car is a 24-bit number and whose cdr is a 36 bit number.
Such values are returned in a "transient" cons with "transient" numbers (meaning
that they must be copied with CONS and/or IPLUS before another value is
called for). This type might be used, for example, for storing the starting
and ending byte positions of expressions printed in the print-region.
2. HASHFILEPROP recognizes two new attributes:
#ENTRIES - returns the total number of entries in the file.
ITEMLENGTH - returns the average number of characters per entry.
These values may be given to CREATEHASHFILE to indicate what the
initial allocations should be when creating a new hash-file based on
an old one.
