Accessing the internet is simple with Blitz. You use something called TCP. Here is a fully commented simple program to show you how to do so. Here, we shall download the index page of my website: ; connect to camphillboys website site = OpenTCPStream("www.camphillboys.bham.sch.uk",80) ; check if a connectiong could be made If Not site Then Print "Connection could not be established." WaitKey() End End If ; ask for contents of page WriteLine site,"GET https://www.camphillboys.bham.sch.uk/home/in05wallis/index.htm HTTP/1.0" WriteLine site,Chr$(10) ; write data to screen While Not Eof(site) Print ReadLine$(site) Wend ; close stream and end program CloseTCPStream site WaitKey() End --v That is a very simple way to download any internet file you wish. Other commands can be sent, and these can be found here.

flying_cucco	From the BB online help: OpenTCPStream/CloseTCPStream Example Print "Connecting..." tcp=OpenTCPStream( "www.blitzbasement.com",80 ) If Not tcp Print "Failed.":WaitKey:End Print "Connected! Sending request..." WriteLine tcp,"GET https://www.blitzbasement.com HTTP/1.0" WriteLine tcp,Chr$(10) If Eof(tcp) Print "Failed.":WaitKey:End Print "Request sent! Waiting for reply..." While Not Eof(tcp) Print ReadLine$( tcp ) Wend If Eof(tcp)=1 Then Print "Success!" Else Print "Error!" CloseTCPStream tcp WaitKey End --v

shroom_monk	Yeah, I did base it on that, but with some modifications.
