Fred:
Thanks for the support.
Check my attempt below which does not work, and offer another suggestion
please. Also, I would think you have been around to know that examples and
descriptions in the help file are often so simple (some would say trite),
that they are not helpful in getting a task done. New and even experienced
users would certainly agree. Thus, requests for help, like mine, are often
made **after** hours spent in the help files and scouring the Message files
does not produce an answer or even a hint. You assume they have not been
read, but often they have and do not answer the question asked.
In this case, it is not only **not** obvious, but impossible so far to
figure out how to get the symbols from the tls file into a variable (what
type?) so they can be added to the Watchlist via the CategoryAddSymbol
command.
Again, the following code does not produce any error messages but nothing
happens with either Scan or Explore (set to current symbol, n=1). I can not
even get the error message in the if/else statement to show up when I enter
a nonexistent filename---where is it supposed to show up?
(Again, so much is missing from the help files that dialog like this is
necessary, even after reading it several times.)
// For Test, use WL 8 Test
WLNum = 8;
IPList = GetCategorySymbols(categoryWatchlist, WLNum);
for (i = 0; i < 999999; i++)
{
TickerNext = StrExtract(IPList, i);
if (TickerNext == "")
i = 999999;
else
CategoryRemoveSymbol(TickerNext, categoryWatchlist, WLNum);
}
// Open and get symbols in TLS
fh = fopen( "C:\Documents and Settings\Owner\My Documents\My
Documents\AmiBroker\_Z_ETFs\DIA.tls", "r");
if( fh )
{
while( ! feof( fh ) )
{
Sym =( fgets( fh ) );
CategoryAddSymbol( Sym, categoryWatchlist, 8);
}
}
else
{
printf("ERROR: file can not be found (does not exist)");
}
Filter=1;
Buy=0;
AddColumn(Close, "Price", 1.2);

Ken,
I already answered your a) & c) questions on another board and provided code
for you to use.
If you are wanting to get the list from a .tls or .txt file then use the
fopen( filename, mode )
command to open whatever file you want to get the list from ... the
fgets( filehandle )
command to read line items from the file ... the
CategoryAddSymbol( symbol, category, number )
To add the symbol(s) to whatever category . and the
fclose( filehandle )
To close the file when you are done.
Books, Documentation & Help Files are wonderful things . especially when
one actually uses them.
