Dennis:
I feel I have a lot to learn from dynamic variables here (asked once
before), but right now I can not make this concept work.
Code below is my modifcation of your concept and it does not crash but only
prints the commas between the strings.
List becomes H1 on the first pass through the loop, then, SymList is SymList
(empty on first pass) + the first (0) item in H1, or the first symbol. At a
minimum, the Symlist will eventually be ",SPY,etc) as there is no logic to
skip the first comma---unless I am reading it wrong. Same issue on each of
the other ShrList and DatList.
So, not sure what I am missing, nor have I been successful in adding
anything to correct the problem.
Any suggestions?
Many thanks for responding.
Ken
==============================
My code using your concept"
H1 = "SPY,500,06/04/2008";
H2 = "DIA,100,09/02/2008";
H3 = "QQQQ,300,08/04/2008";
H4 = "BEARX,1204,05/21/2007";
TotalSymbolCount = 4;
SymList = "";
ShrList = "";
DatList = "";
for( i=1; i < totalSymbolCount; i++ )
{
list = StaticVarGetText( "H" + NumToStr(i, 1.0, 0));
SymList = SymList + "," + StrExtract( list , 0);
ShrList = ShrList + "," + StrExtract( list, 1);
DatList = DatList + "," + StrExtract( list, 2);
}
Title = Symlist + "\n" +
ShrList + "\n" +
DatList;

Ken,
This is quite easy by using the StrExtract( list, item) function. I am
doing some similar things in the AFL I am writing for the AFL Glossary
project.
Typing this off the top of my head to give you the basic idea:
For( i=1; i < totalSymbolCount; i++ )
{
list = VarGetText( "H" + NumToStr(i, 1.0, 0);
SymList = SymList + "," + StrExtract( list , 0);
ShrList = ShrList + "," + StrExtract( list, 1);
DatList = DatList + "," + StrExtract( list, 2);
}
BR,
Dennis

I have tried various constructions to achieve the following, but the code
gets complex and has no good way of detecting end of string.
I would like to take a series of strings, H1, H2, H3, and create lists of
the elements, as such
H1 = "SPY,500,06/04/2008";
H2 = "DIA,100,09/02/2008";
H3 = "QQQQ,300,08/04/2008";
and turn them into these three lists
SymList = "SPY,DIA,"QQQQ";
ShrList = "500,100,300";
DatList = "06/04/2008,09/02/2008,08/04/2008";
Hx strings would be hard coded into the overall afl although one could set
up a variety of paramtxt statements to enter them.
Seems like it would be somewhat easy (and maybe it is), but I get bogged
down in switch/case statements, or complex if/else statements.
Anyone see a more simple way to arrange the strings.
My ultimate goal is to have a list of "holdings" and some simple statistics
displayed.
AA window with a Watchlist seems obvious--yes?--but I need to have multiple
positions of the same symbol, and I do not think you can put multiples of
the same symbol in a watchlist--same symbol with different shares purchased
on different dates-- (is there a way?).
I next tried dynamic variables, in order to manipulate symbols and their
associated price statistics, but that bombed.
So now I am attempting to display my list of holdings in a Gfx title
statement.
I successfully have it displayed, but using long strings, like above for the
SymList, ShrList, and DatList. This gets unmanageable when the number of
symbols gets large and you try, by eye, to coordinate the dates and shares.
Thus, I was hoping to list a three element string reprenting each holding
and then rearrage them into long string lists.
any ideas?
thanks.
