You would also need to add the comma handling, as was done in the
sample that I gave.
If you wanted to combine the two approaches, you could just have the
loop call the addPosition procedure, else move the addPosition
procedure logic into your loop.
VarSetText("H1", "SPY,500,06/04/2008");
...
totalSymbolCount = ...;
for (i = 1; i <= totalSymbolCount; i++) {
addPosition(VarGetText("H" + i));
}
Using a procedure helps get rid of the clutter from your primary
logic, at the expense of an additional function call. Similarly, it is
probably faster to use direct variable referencing rather than
VarGetText/VarSetText and a loop. But, if you anticipate many "H"
values, the dynamic variables will keep things more succinct and
easier to maintain.
