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.
