Has anyone tried to use the Unix/Windows SOCKET procedure in IDL V5.4,
or thought about ways that it might be useful? It looks to me like
it should allow one to read a file on an anonymous FTP server, but I
haven't figured out the syntax for this. (I have no previous socket
programming experience in other languages, so I am proceeding
naively...)
For example, I can open a socket to an anonymous FTP account on a
machine named 'ftpservername'
IDL> socket, 1, 'ftpservername', 'ftp'
and read the welcome message
IDL> text = ''
IDL> readf,1,text & print,text
but I haven't figured out the syntax for reading a file on
the FTP server. I'd also be interested in hearing of other possible
applications for the SOCKET procedure. Is it mainly for use with a C
interface, or is it useful in pure IDL applications?
