You may have noticed that it requires almost
zero time to find any item in the stock table
by the stock number. This is because all of
the stock numbers are indexed and held in
memory by the program. Unfortunately there is
limited memory in DOS software to do this.
The theoretical maximum would be 32,000 items
but since some memory must also be used for
other purposes the program becomes unstable
with more than 26,000 items.
The other consideration is that one of the
reasons that this program is free is to help
the small to medium business compete with the
Wal-Marts of this world. With some exceptions
once a retail business grows large enough to
carry more than 26,000 different items then
it is a Wal-Mart type large business and
should be able to afford commercially produced
POS software.
