CHANGES FOR VERSION 6.17.0 (as compared to 6.16.0)

• AFL: Changed default number formatting string from “%g” to “%.7g” (so 7 significant digits are now displayed instead of 6)

• AFL: new function InternetClose( handle )
• AFL: new function InternetOpenURL( “url” )
• AFL: new function InternetReadString( handle ) – read a string (line) from internet resource
• AFL: printf/StrFormat/TRACEF support now “%s” (string specifier) and accept string arguments passed and made faster too
• Data: Gics.txt classification updated (thanks to PremiumData)
• OLE Automation: individual backtest is now supported via OLE automation
• OLE: Interval property of Document object is now writable so you can set chart interval from OLE
• Startup is made faster
• UI: AFL Editor MDI UI did not get immediate refresh after file name change when main window was in modal state due to the way how MFC works. Fixed.
• UI: File->Database Settings, default maximum “number of bars” increased to 1 million
• UI: New Analysis Settings submenu is now duplicated in main window Analysis->Options menu for easier access for beginners

NOTE:
If End-Of-File has been reached, the function returns empty string ("")
If End-of-File has NOT been reached, the function always returns non-empty string because each line read by this function ends with new line character "\n",
so if server has sent empty line it will be read as "\n"
You can trim new line characters using StrTrim

Internet* functions open wide area of applications including:
1. querying web APIs for extra data
2. using web/rest APIs for communication ( sending messages/alerts to Twitter, SMS gateways, etc)

Example:

ih = InternetOpenURL( "https://www.quandl.com/api/v3/datasets/SEC/AAPL_SALESREVENUENET_Q.csv?api_key=" );
printf( "AAPL Revenue:\n" );
if( ih )
{
     while( ( str = InternetReadString( ih ) ) != "" )
     {
         printf( "%s", str );
     }
     InternetClose( ih );
}
