hi,
I wanted to use multi dimensional arrays so that I
can use a number of levels as a variable. It is impossible in Amibroker to
define a variable number of arrays, or I do not know how. For instance I tried
as a variable: nlev = 4;
for (k = 0; k <= nlev * 2; k++)
{
nn = (k -
nlev);
global "lev" + nn;
"lev + nn = Null;
}
this does not work. So it seems you can not define
a variable number of "normal" arrays.
Therefor I moved to static arrays. That
seemed to work at first but I encountered problems I did not understand and now
I find this in the manual: "static array variables store only as many bars as there
are currently in use by given chart." Even though I use setbarsrequired(-2,-2)
or setbarsrequired(sbrall) the values inside the static arrays seem to vary. It
depends where you drop your cursor, what part of the chart you display how they
get filled. I thought there was something wrong in my code, drives you nuts but
the values in these static arrays seem all over the place, pretty much
useless for my purposes. Attached code what I was trying to do. Also I get
different results when using setbarsrequired(-2,-2) and
setbarsrequired(sbrall).
Now I turned to the Osaka plugin but I find that you can
fill and restore only 1 element at a time. You can not get an entire row at
once. Am I right?
thanks, Ed

The changes made by Tomasz to the OSAKA plugin are documented in the
readme.

ok thanks. I only find it in the 3-rd
party area. Seems to be unchanged. Didn't know Tomasz improved it. Looks the
same from when I tried it a few years ago. It has very little documentation.
Will try again some day.
to reefbreak: will have a look. For now I am
able to solve my problem using static arrays. I am writing a
complicated scaling in and out system, at least complicated to code where at
the entry signal I define levels for scaling in and out. It looks like I can
do without these multi dimensional arrays and static arrays do the
job.

Re: [amibroker] Re: ABTool / multidimensional arrays
btw, if you haven't tried the OSAKA plugin yet you should give it a
try. Tomasz improved it some time in the past and it gives, if you use it
is intended to be used, high performance multi-column sorting. It is fast
and has full capability to save/read/import tables to/from files - also
very fast. It offers an unlimited number of columns, this may enable you
to simulate multi dimensional tables in a two dimensional field.
I
think there are some ready to run examples in file section.
If you
haven't used this plugin you are missing out on some great functions! I
encourage you to try it.

You didn't state your application, so I don't know if it is relevant, but I posted a 2 dimensional sort routine in message 136551. This routine reverse sorts tickers and an indicator value, and keeps the pairs together to be printed in the Interpretation window.

The last I heard was that the developer stopped supporting it and that Tomasz wrote at some point that ABTools wasn't compatible with AB. It would be risky to use it.

hi,
I was looking into multidimensional arrays again. I know there is the Osaka plugin but never quite figured out how to use it. However, I found this post:
http://finance.groups.yahoo.com/group/amibroker/message/40135
all the way from 2003. This ABTool seems just what I need and easy to understand. However it seems to have been removed. Anyone know the history on this? Why it has been removed? What is currently the status with multidimensional arrays in Amibroker?
thanks, Ed
