Thanks Mike for pointing out that += works with strings also.
Oh, yea, the comma at the beginning.
I would get around that by doing the following:
for( i=1; i < totalSymbolCount; i++ )
{
list = StaticVarGetText( "H" + NumToStr(i, 1.0, 0));
if(i==1){comma = "";} else{comma = ",";}
SymList += comma + StrExtract( list , 0);
ShrList += comma + StrExtract( list, 1);
DatList += comma + StrExtract( list, 2);
}
Ken, you now have the best ideas of three people.
BR,
Dennis
