BP2 takes care of the size of the
(the item being computed) and expands its work space when necessary. You may
want to control it, notably when using a length-increasing grammar. Dialog
"Buffer size" (see Fig.23) displays the current buffer size and the default one
assigned when computation starts. Suppose that you do not want to produce a
string longer than 750 symbols. Type "750" in the upper field and any
in the default field, then select "use". Now BP2 computes items until the
length of the work string reaches 750 symbols, then it prompts you to decide
whether you want to stop or continue (expanding the current work space).
project (see §5.4 infra), default buffer size is set to 500 symbols but
all items need more space. Therefore, BP2 is forced to expand its space for
the work string the first time it produces an item. It does so without asking
any permission because the "Don't sto
option is on. The new value is stored into dialog "Buffer siz
(Buffer expansion is done stepwise: size is recurrently multiplied by 3/2.)
a very high default value reduces the memory available for other operations.
Setting a too small one reduces speed during the first computation, as BP2
needs to resize the work string buffer more often.
