[ about the need for more speed for some things ....]
Example: The HotKeyN2O stack stores all properties of all
controls in a card when the user opens the card. The props
are all in array form which cannot be stored into another
array (time based array of object changes). So for each
object i have to translate array[key]=data to <key>data</key>.
This in turn is stored into a time-based array. So if i need
to restore the property (any) for any object and at any time,
it's ultra easy - except that the translation process is so
slow after 10 controls trasnlated that it's USELESS if i dont
write that into a real-compiled external.
I agree with you about the need for more speed for some applications
(and sorry Dan, but I've seen requests for more speed a number of times
on this list ... sometimes they can be overcome by creative use of
Transcript's features in unusual ways, but I'm not convinced that's
always possible, nor that it should be necessary to use non-obvious
programming tricks, at the cost of loss of readability and
maintainability, when some improvements in native performance would do
it better)
But in this example, there may be a better way to organize your (Mr.
X's) data that would be fast enough. 2 possibilities I see
1. data[key] contains
time of change, the new value
time of change, the new value
etc.
then you can directly index the individual property, then find the
appropriate line entry (which you'd keep sorted). If you needed to, you
could then binary search through the lines for the most recent change
before the time desired..
2. the data is in a time-based array, but as a 'combine'd array-as-list.
So you'd simply
find the array entry based on time put data[theTime] into myProps
split myProps by cr and comma
so the value of a property would be myProp[theProp]
Not sure which of those would be better - depends on the full set of
operations you need to do.
