A thought on why HP28 operations on a list of 100 items might be
reasonably fast, while those on a list of 200 are much slower. If the
HP28 memory is nearly full when you have a list of 200 objects, then
theHP28 might be spending an inordinate amount of time doing repeated
garbage collection every time it gets really short of memory. Try
freeing up some memory - delete unwanted variables if possible. If not,
disable ONE of the LAST options (despite my message yestaerday warning
against disabling LAST options, this sometimes is necessary, but if at
all possible, disable either the stack or the argument saving, not both;
in this case, if you are editing long strings it may be best to disable
the command option).
