take an example, you want to apply moving average
on another moving average on another moving average,
etc.
in Easylang, you can just pile them up
average (average (average ( ... )))
Easylang will calc each average only once and remember
each as a separate series. a type of optimization
since it is specifically made to work that way.
in any other script lang,
average (average (average (expression, ...)))
the expression will have to be treated something
that will be recalculated on the fly and each time
the above line is called, all the calculations will
be repeated again and again, all the time.
This problem is not noticable because nowadays our
computers are way faster than before ...
unless you have some very complex calculation
on hand ....

the optimization of easylang on handling series
made it easier to mix series and numbers, but
then how should one handle say a multidimensional
matrix of series ?! it cannot.
In a normal programming lang, you can then
have a matrix of pointers or objects, where each
of these objects are series themselves. Maybe
harder to do in VB, but definitely a breeze in
object pascal, c++, java, etc.

My point in the original mesg is about how the
users of easylang outgrew its power. Unluckily
it is hard for most users of easylang to switch
to other programming language because easylang
is just different.
In short Omega did something great in the beginning
with TS and its programming lang. But that era is
gone and the programmers who did the marvels for
Omega had all left the company years ago.
TS4 is a total rewrite of TS3, and then TS2000 is a
total rewrite of TS4. Thus we cannot expect the
stability of TS3.
