I am trying to do some repetitive string manipulations, and keep getting
errors when trying to use a function.
Can you help me out with this simplified code to exemplify what I am trying
to do.
Lets say I have a series of strings like this:
T1 = "DODFX 06/10/2007 50.78 ";
T2 = "JORNX 07/13/2007 11.84";
The contents are obvious, and I would like to set up some code which cycles
through these strings and extracts the relevant data.
In Logic, Loop through each string, extract Sym, Date, Purchase Price,
calculate some stats, Print a line of results in an Explore grid.
I tried code like this:
function GetData(VarA)
{
Sym1 = StrMid(VarA,1,5);
BuyDate1 = StrMid(VarA,7,10);
BuyPrice1 = StrToNum(StrMid(VarA,19,5));
P1 = Foreign(Sym1,"C");
D1 = LastValue(P1) - BuyPrice1;
Pct1 = 100 * (P1 - BuyPrice1)/BuyPrice1;
return Sym1;
}
then this:
function PrintLine(Sym1,BuyDate1,BuyPrice1,P1,D1)
{
AddTextColumn(Sym1,"Symbol",1.0);
AddTextColumn(BuyDate1,"BuyDate",1.0);
AddColumn(BuyPrice1,"BuyPrice",1.2);
AddColumn(P1,"CurPrice",1.2);
AddColumn(D1,"Gain",1.2);
AddColumn(Pct1,"PcntGain",1.2);
}
for( i = 1; i < 3; i++ )
{
if (i == 1) XX = T1;
if (i == 2) XX = T2;
YY = GetData(XX);
_TRACE(Sym1);
PrintLine(Sym1,BuyDate1,BuyPrice1,P1,D1);
}
However, I can not get past the first step of recognizing the first
variable, Sym1 (Error: Sym1 has not been initialized).
I thought once I call the function, that the pass through the function
establishes the variables contained within the function. IOW, the first
call to GetData(VarA) establishes the Variable "Sym1". This does not seem
to be the case.
So what might I do differently? At least to get the GetData function to
operate properly. I have several other questions but would appreciate
getting at least this far.
Thanks for any help.
