FtpPut session, srcFile$, dstFile$
This command uploads a file to an open FTP session. You must specify the name of the file to upload srcFile$ and the name to save the file as on the FTP server dstFile$. dstFile$ will be stored relative to the current working directory on the FTP server. All internet connections are subject to interruption at any time so check FtpGetError$(n) and FtpGetReply$(n) after each FTP command you execute.
