Hi James,
I would probably do
try
with MyStringList do
So I could just do this?
Index:= MyStringlist.IndexOfName(SearchName);
If Index >=0 then
MyValue := MyStringlist[Index].ValueFromIndex;
That sure is nice to know, Thank you!
I guess for my dynamic arrays of records, I still need to search with a
loop... or is there a cool thing I don't

Hi James,
You don't need a loop for that:
index:=MyStringlist.IndexOfName;

martin.
The problem with the for in loop is that I need the index.
I'm sometimes searching through the stringlist looking for a match, and when I
find a match, I want to read the value
And then do a break, because there is no point is searching once I found what I
am looking for:
For I:= 0 to

As Bart suggested, you can use too the for/in loop: for s in sl do
WriteLn( s);
For example:
var
sl: TStringList;
s: String;
begin
sl:= TStringList.Create;
try
sl.Add('1');
sl.Add('2');
for s in sl do WriteLn( s);
finally
FreeAndNil(
The loops is just an example because in my original post of why I wanted to
get the highest element of a stringlist was because I wanted a for loop that
wasn't as clumsy as
For I:=0 to myStringlist.count-1 Do
This came up because thanks to this discussion list, I learned I could use
High() and

Because support for the "class" keyword is only available when the
modeswitch Class is enabled which is the case

I don't understand what is wrong with Count-1, but you can get the
highest index like this if you wish:
Thank you for the example! I also needed
{$Mode OBJFPC}
to get it working. I am normally in
{$Mode FPC} Or {$Mode TP}
But I found that if I just put this in a unit that is {$Mode OBJFPC} and
include that unit in my {$Mode TP} Unit it works just great!
I have a useless unit that is just a

It would be nice to not have the -1
Could High() be made to work if the argument was a
